Adapted Material means material subject to Copyright and Similar + Rights that is derived from or based upon the Licensed Material + and in which the Licensed Material is translated, altered, + arranged, transformed, or otherwise modified in a manner requiring + permission under the Copyright and Similar Rights held by the + Licensor. For purposes of this Public License, where the Licensed + Material is a musical work, performance, or sound recording, + Adapted Material is always produced where the Licensed Material is + synched in timed relation with a moving image. + + b. Adapter's License means the license You apply to Your Copyright + and Similar Rights in Your contributions to Adapted Material in + accordance with the terms and conditions of this Public License. + + c. BY-SA Compatible License means a license listed at + creativecommons.org/compatiblelicenses, approved by Creative + Commons as essentially the equivalent of this Public License. + + d. Copyright and Similar Rights means copyright and/or similar rights + closely related to copyright including, without limitation, + performance, broadcast, sound recording, and Sui Generis Database + Rights, without regard to how the rights are labeled or + categorized. For purposes of this Public License, the rights + specified in Section 2(b)(1)-(2) are not Copyright and Similar + Rights. + + e. Effective Technological Measures means those measures that, in the + absence of proper authority, may not be circumvented under laws + fulfilling obligations under Article 11 of the WIPO Copyright + Treaty adopted on December 20, 1996, and/or similar international + agreements. + + f. Exceptions and Limitations means fair use, fair dealing, and/or + any other exception or limitation to Copyright and Similar Rights + that applies to Your use of the Licensed Material. + + g.

Licensed Material means the artistic or literary work, database, + or other material to which the Licensor applied this Public + License. + + i.

Sui Generis Database Rights means rights other than copyright + resulting from Directive 96/9/EC of the European Parliament and of + the Council of 11 March 1996 on the legal protection of databases, + as amended and/or succeeded, as well as other essentially + equivalent rights anywhere in the world. + + m. You means the individual or entity exercising the Licensed Rights + under this Public License. Your has a corresponding meaning. + + +Section 2 -- Scope. + + a. License grant. + + 1.

Exceptions and Limitations. For the avoidance of doubt, where + Exceptions and Limitations apply to Your use, this Public + License does not apply, and You do not need to comply with + its terms and conditions. + + 3. Term. The term of this Public License is specified in Section + 6(a). + + 4. Media and formats; technical modifications allowed. The + Licensor authorizes You to exercise the Licensed Rights in + all media and formats whether now known or hereafter created, + and to make technical modifications necessary to do so. The + Licensor waives and/or agrees not to assert any right or + authority to forbid You from making technical modifications + necessary to exercise the Licensed Rights, including + technical modifications necessary to circumvent Effective + Technological Measures. For purposes of this Public License, + simply making modifications authorized by this Section 2(a) + (4) never produces Adapted Material. + + 5. Downstream recipients. + + a. Offer from the Licensor -- Licensed Material. Every + recipient of the Licensed Material automatically + receives an offer from the Licensor to exercise the + Licensed Rights under the terms and conditions of this + Public License. + + b. Additional offer from the Licensor -- Adapted Material. + Every recipient of Adapted Material from You + automatically receives an offer from the Licensor to + exercise the Licensed Rights in the Adapted Material + under the conditions of the Adapter's License You apply. + + c. No downstream restrictions. You may not offer or impose + any additional or different terms or conditions on, or + apply any Effective Technological Measures to, the + Licensed Material if doing so restricts exercise of the + Licensed Rights by any recipient of the Licensed + Material. + + 6. No endorsement. Nothing in this Public License constitutes or + may be construed as permission to assert or imply that You + are, or that Your use of the Licensed Material is, connected + with, or sponsored, endorsed, or granted official status by, + the Licensor or others designated to receive attribution as + provided in Section 3(a)(1)(A)(i). + + b. Other rights. + + 1. Moral rights, such as the right of integrity, are not + licensed under this Public License, nor are publicity, + privacy, and/or other similar personality rights; however, to + the extent possible, the Licensor waives and/or agrees not to + assert any such rights held by the Licensor to the limited + extent necessary to allow You to exercise the Licensed + Rights, but not otherwise. + + 2. Patent and trademark rights are not licensed under this + Public License. + + 3. To the extent possible, the Licensor waives any right to + collect royalties from You for the exercise of the Licensed + Rights, whether directly or through a collecting society + under any voluntary or waivable statutory or compulsory + licensing scheme. In all other cases the Licensor expressly + reserves any right to collect such royalties. + + +Section 3 -- License Conditions. + +Your exercise of the Licensed Rights is expressly made subject to the +following conditions. + + a. Attribution. + + 1. If You Share the Licensed Material (including in modified + form), You must: + + a. retain the following if it is supplied by the Licensor + with the Licensed Material: + + i. identification of the creator(s) of the Licensed + Material and any others designated to receive + attribution, in any reasonable manner requested by + the Licensor (including by pseudonym if + designated); + + ii. a copyright notice; + + iii. a notice that refers to this Public License; + + iv. a notice that refers to the disclaimer of + warranties; + + v. a URI or hyperlink to the Licensed Material to the + extent reasonably practicable; + + b. indicate if You modified the Licensed Material and + retain an indication of any previous modifications; and + + c. indicate the Licensed Material is licensed under this + Public License, and include the text of, or the URI or + hyperlink to, this Public License. + + 2. You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in + which You Share the Licensed Material. For example, it may be + reasonable to satisfy the conditions by providing a URI or + hyperlink to a resource that includes the required + information. + + 3. If requested by the Licensor, You must remove any of the + information required by Section 3(a)(1)(A) to the extent + reasonably practicable. + + b. ShareAlike. + + In addition to the conditions in Section 3(a), if You Share + Adapted Material You produce, the following conditions also apply. + + 1. The Adapter's License You apply must be a Creative Commons + license with the same License Elements, this version or + later, or a BY-SA Compatible License. + + 2. You must include the text of, or the URI or hyperlink to, the + Adapter's License You apply. You may satisfy this condition + in any reasonable manner based on the medium, means, and + context in which You Share Adapted Material. + + 3. You may not offer or impose any additional or different terms + or conditions on, or apply any Effective Technological + Measures to, Adapted Material that restrict exercise of the + rights granted under the Adapter's License You apply. + + +Section 4 -- Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that +apply to Your use of the Licensed Material: + + a. for the avoidance of doubt, Section 2(a)(1) grants You the right + to extract, reuse, reproduce, and Share all or a substantial + portion of the contents of the database; + + b. if You include all or a substantial portion of the database + contents in a database in which You have Sui Generis Database + Rights, then the database in which You have Sui Generis Database + Rights (but not its individual contents) is Adapted Material, + including for purposes of Section 3(b); and + + c. You must comply with the conditions in Section 3(a) if You Share + all or a substantial portion of the contents of the database. + +For the avoidance of doubt, this Section 4 supplements and does not +replace Your obligations under this Public License where the Licensed +Rights include other Copyright and Similar Rights. + + +Section 5 -- Disclaimer of Warranties and Limitation of Liability. + + a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE + EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS + AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF + ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, + IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, + WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR + PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, + ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT + KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT + ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. + + b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE + TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, + NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, + INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, + COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR + USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN + ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR + DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR + IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. + + c. The disclaimer of warranties and limitation of liability provided + above shall be interpreted in a manner that, to the extent + possible, most closely approximates an absolute disclaimer and + waiver of all liability. + + +Section 6 -- Term and Termination. + + a. This Public License applies for the term of the Copyright and + Similar Rights licensed here. However, if You fail to comply with + this Public License, then Your rights under this Public License + terminate automatically. + + b. Where Your right to use the Licensed Material has terminated under + Section 6(a), it reinstates: + + 1. automatically as of the date the violation is cured, provided + it is cured within 30 days of Your discovery of the + violation; or + + 2. upon express reinstatement by the Licensor. + + For the avoidance of doubt, this Section 6(b) does not affect any + right the Licensor may have to seek remedies for Your violations + of this Public License. + + c. For the avoidance of doubt, the Licensor may also offer the + Licensed Material under separate terms or conditions or stop + distributing the Licensed Material at any time; however, doing so + will not terminate this Public License. + + d. Sections 1, 5, 6, 7, and 8 survive termination of this Public + License. + + +Section 7 -- Other Terms and Conditions. + + a. The Licensor shall not be bound by any additional or different + terms or conditions communicated by You unless expressly agreed. + + b. Any arrangements, understandings, or agreements regarding the + Licensed Material not stated herein are separate from and + independent of the terms and conditions of this Public License. + + +Section 8 -- Interpretation. + + a. For the avoidance of doubt, this Public License does not, and + shall not be interpreted to, reduce, limit, restrict, or impose + conditions on any use of the Licensed Material that could lawfully + be made without permission under this Public License. + + b. To the extent possible, if any provision of this Public License is + deemed unenforceable, it shall be automatically reformed to the + minimum extent necessary to make it enforceable. If the provision + cannot be reformed, it shall be severed from this Public License + without affecting the enforceability of the remaining terms and + conditions. + + c. No term or condition of this Public License will be waived and no + failure to comply consented to unless expressly agreed to by the + Licensor. + + d. Nothing in this Public License constitutes or may be interpreted + as a limitation upon, or waiver of, any privileges and immunities + that apply to the Licensor or You, including from the legal + processes of any jurisdiction or authority. + + +======================================================================= + +Creative Commons is not a party to its public +licenses.

Presets begin with a digit 0-9 and may be followed by zero or more flags which are lower-case letters. Currently only "e" is supported, matching LZMA_PRESET_EXTREME. For partial xz command line syntax compatibility, a preset string may start with a single dash "-".</p> +<p>A filter chain consists of one or more "filtername:opt1=value1,opt2=value2" strings separated by one or more spaces. Leading and trailing spaces are ignored. All names and values must be lower-case. Extra commas in the option list are ignored. The order of filters is significant: when encoding, the uncompressed input data goes to the leftmost filter first.

The native file format is the .xz + format, but the legacy .lzma format used by LZMA Utils and raw com- + pressed streams with no container format headers are also supported. + In addition, decompression of the .lz format used by lzip is supported. + + xz compresses or decompresses each file according to the selected oper- + ation mode. If no files are given or file is -, xz reads from standard + input and writes the processed data to standard output. xz will refuse + (display an error and skip the file) to write compressed data to stan- + dard output if it is a terminal. Similarly, xz will refuse to read + compressed data from standard input if it is a terminal. + + Unless --stdout is specified, files other than - are written to a new + file whose name is derived from the source file name: + + o When compressing, the suffix of the target file format (.xz or + .lzma) is appended to the source filename to get the target file- + name. + + o When decompressing, the .xz, .lzma, or .lz suffix is removed from + the filename to get the target filename. xz also recognizes the + suffixes .txz and .tlz, and replaces them with the .tar suffix. + + If the target file already exists, an error is displayed and the file + is skipped. + + Unless writing to standard output, xz will display a warning and skip + the file if any of the following applies: + + o File is not a regular file. Symbolic links are not followed, and + thus they are not considered to be regular files. + + o File has more than one hard link. + + o File has setuid, setgid, or sticky bit set. + + o The operation mode is set to compress and the file already has a + suffix of the target file format (.xz or .txz when compressing to + the .xz format, and .lzma or .tlz when compressing to the .lzma for- + mat). + + o The operation mode is set to decompress and the file doesn't have a + suffix of any of the supported file formats (.xz, .txz, .lzma, .tlz, + or .lz). + + After successfully compressing or decompressing the file, xz copies the + owner, group, permissions, access time, and modification time from the + source file to the target file. If copying the group fails, the per- + missions are modified so that the target file doesn't become accessible + to users who didn't have permission to access the source file. xz + doesn't support copying other metadata like access control lists or ex- + tended attributes yet. + + Once the target file has been successfully closed, the source file is + removed unless --keep was specified. The source file is never removed + if the output is written to standard output or if an error occurs. + + Sending SIGINFO or SIGUSR1 to the xz process makes it print progress + information to standard error. This has only limited use since when + standard error is a terminal, using --verbose will display an automati- + cally updating progress indicator. + + Memory usage + The memory usage of xz varies from a few hundred kilobytes to several + gigabytes depending on the compression settings. The settings used + when compressing a file determine the memory requirements of the decom- + pressor. Typically the decompressor needs 5 % to 20 % of the amount of + memory that the compressor needed when creating the file. For example, + decompressing a file created with xz -9 currently requires 65 MiB of + memory. Still, it is possible to have .xz files that require several + gigabytes of memory to decompress. + + Especially users of older systems may find the possibility of very + large memory usage annoying. To prevent uncomfortable surprises, xz + has a built-in memory usage limiter, which is disabled by default. + While some operating systems provide ways to limit the memory usage of + processes, relying on it wasn't deemed to be flexible enough (for exam- + ple, using ulimit(1) to limit virtual memory tends to cripple mmap(2)). + + The memory usage limiter can be enabled with the command line option + --memlimit=limit. Often it is more convenient to enable the limiter by + default by setting the environment variable XZ_DEFAULTS, for example, + XZ_DEFAULTS=--memlimit=150MiB. It is possible to set the limits sepa- + rately for compression and decompression by using --memlimit-com- + press=limit and --memlimit-decompress=limit. Using these two options + outside XZ_DEFAULTS is rarely useful because a single run of xz cannot + do both compression and decompression and --memlimit=limit (or -M + limit) is shorter to type on the command line. + + If the specified memory usage limit is exceeded when decompressing, xz + will display an error and decompressing the file will fail. If the + limit is exceeded when compressing, xz will try to scale the settings + down so that the limit is no longer exceeded (except when using --for- + mat=raw or --no-adjust). This way the operation won't fail unless the + limit is very small. The scaling of the settings is done in steps that + don't match the compression level presets, for example, if the limit is + only slightly less than the amount required for xz -9, the settings + will be scaled down only a little, not all the way down to xz -8. + + Concatenation and padding with .xz files + It is possible to concatenate .xz files as is. xz will decompress such + files as if they were a single .xz file. + + It is possible to insert padding between the concatenated parts or af- + ter the last part. The padding must consist of null bytes and the size + of the padding must be a multiple of four bytes. This can be useful, + for example, if the .xz file is stored on a medium that measures file + sizes in 512-byte blocks. + + Concatenation and padding are not allowed with .lzma files or raw + streams. + +OPTIONS + Integer suffixes and special values + In most places where an integer argument is expected, an optional suf- + fix is supported to easily indicate large integers. There must be no + space between the integer and the suffix. + + KiB Multiply the integer by 1,024 (2^10). Ki, k, kB, K, and KB are + accepted as synonyms for KiB. + + MiB Multiply the integer by 1,048,576 (2^20). Mi, m, M, and MB are + accepted as synonyms for MiB. + + GiB Multiply the integer by 1,073,741,824 (2^30). Gi, g, G, and GB + are accepted as synonyms for GiB. + + The special value max can be used to indicate the maximum integer value + supported by the option. + + Operation mode + If multiple operation mode options are given, the last one takes ef- + fect. + + -z, --compress + Compress. This is the default operation mode when no operation + mode option is specified and no other operation mode is implied + from the command name (for example, unxz implies --decompress). + + -d, --decompress, --uncompress + Decompress. + + -t, --test + Test the integrity of compressed files. This option is equiva- + lent to --decompress --stdout except that the decompressed data + is discarded instead of being written to standard output. No + files are created or removed. + + -l, --list + Print information about compressed files. No uncompressed out- + put is produced, and no files are created or removed. In list + mode, the program cannot read the compressed data from standard + input or from other unseekable sources. + + The default listing shows basic information about files, one + file per line. To get more detailed information, use also the + --verbose option. For even more information, use --verbose + twice, but note that this may be slow, because getting all the + extra information requires many seeks. The width of verbose + output exceeds 80 characters, so piping the output to, for exam- + ple, less -S may be convenient if the terminal isn't wide + enough. + + The exact output may vary between xz versions and different lo- + cales. For machine-readable output, --robot --list should be + used. + + Operation modifiers + -k, --keep + Don't delete the input files. + + Since xz 5.2.6, this option also makes xz compress or decompress + even if the input is a symbolic link to a regular file, has more + than one hard link, or has the setuid, setgid, or sticky bit + set. The setuid, setgid, and sticky bits are not copied to the + target file. In earlier versions this was only done with + --force. + + -f, --force + This option has several effects: + + o If the target file already exists, delete it before compress- + ing or decompressing. + + o Compress or decompress even if the input is a symbolic link + to a regular file, has more than one hard link, or has the + setuid, setgid, or sticky bit set. The setuid, setgid, and + sticky bits are not copied to the target file. + + o When used with --decompress --stdout and xz cannot recognize + the type of the source file, copy the source file as is to + standard output. This allows xzcat --force to be used like + cat(1) for files that have not been compressed with xz. Note + that in future, xz might support new compressed file formats, + which may make xz decompress more types of files instead of + copying them as is to standard output. --format=format can + be used to restrict xz to decompress only a single file for- + mat. + + -c, --stdout, --to-stdout + Write the compressed or decompressed data to standard output in- + stead of a file. This implies --keep. + + --single-stream + Decompress only the first .xz stream, and silently ignore possi- + ble remaining input data following the stream. Normally such + trailing garbage makes xz display an error. + + xz never decompresses more than one stream from .lzma files or + raw streams, but this option still makes xz ignore the possible + trailing data after the .lzma file or raw stream. + + This option has no effect if the operation mode is not --decom- + press or --test. + + --no-sparse + Disable creation of sparse files. By default, if decompressing + into a regular file, xz tries to make the file sparse if the de- + compressed data contains long sequences of binary zeros. It + also works when writing to standard output as long as standard + output is connected to a regular file and certain additional + conditions are met to make it safe. Creating sparse files may + save disk space and speed up the decompression by reducing the + amount of disk I/O. + + -S .suf, --suffix=.suf + When compressing, use .suf as the suffix for the target file in- + stead of .xz or .lzma. If not writing to standard output and + the source file already has the suffix .suf, a warning is dis- + played and the file is skipped. + + When decompressing, recognize files with the suffix .suf in ad- + dition to files with the .xz, .txz, .lzma, .tlz, or .lz suffix. + If the source file has the suffix .suf, the suffix is removed to + get the target filename. + + When compressing or decompressing raw streams (--format=raw), + the suffix must always be specified unless writing to standard + output, because there is no default suffix for raw streams. + + --files[=file] + Read the filenames to process from file; if file is omitted, + filenames are read from standard input. Filenames must be ter- + minated with the newline character. A dash (-) is taken as a + regular filename; it doesn't mean standard input. If filenames + are given also as command line arguments, they are processed be- + fore the filenames read from file. + + --files0[=file] + This is identical to --files[=file] except that each filename + must be terminated with the null character. + + Basic file format and compression options + -F format, --format=format + Specify the file format to compress or decompress: + + auto This is the default. When compressing, auto is equiva- + lent to xz. When decompressing, the format of the input + file is automatically detected. Note that raw streams + (created with --format=raw) cannot be auto-detected. + + xz Compress to the .xz file format, or accept only .xz files + when decompressing. + + lzma, alone + Compress to the legacy .lzma file format, or accept only + .lzma files when decompressing. The alternative name + alone is provided for backwards compatibility with LZMA + Utils. + + lzip Accept only .lz files when decompressing. Compression is + not supported. + + The .lz format version 0 and the unextended version 1 are + supported. Version 0 files were produced by lzip 1.3 and + older. Such files aren't common but may be found from + file archives as a few source packages were released in + this format. People might have old personal files in + this format too. Decompression support for the format + version 0 was removed in lzip 1.18. + + lzip 1.4 and later create files in the format version 1. + The sync flush marker extension to the format version 1 + was added in lzip 1.6. This extension is rarely used and + isn't supported by xz (diagnosed as corrupt input). + + raw Compress or uncompress a raw stream (no headers). This + is meant for advanced users only. To decode raw streams, + you need use --format=raw and explicitly specify the fil- + ter chain, which normally would have been stored in the + container headers. + + -C check, --check=check + Specify the type of the integrity check. The check is calcu- + lated from the uncompressed data and stored in the .xz file. + This option has an effect only when compressing into the .xz + format; the .lzma format doesn't support integrity checks. The + integrity check (if any) is verified when the .xz file is decom- + pressed. + + Supported check types: + + none Don't calculate an integrity check at all. This is usu- + ally a bad idea. This can be useful when integrity of + the data is verified by other means anyway. + + crc32 Calculate CRC32 using the polynomial from IEEE-802.3 + (Ethernet). + + crc64 Calculate CRC64 using the polynomial from ECMA-182. This + is the default, since it is slightly better than CRC32 at + detecting damaged files and the speed difference is neg- + ligible. + + sha256 Calculate SHA-256. This is somewhat slower than CRC32 + and CRC64. + + Integrity of the .xz headers is always verified with CRC32. It + is not possible to change or disable it. + + --ignore-check + Don't verify the integrity check of the compressed data when de- + compressing. The CRC32 values in the .xz headers will still be + verified normally. + + Do not use this option unless you know what you are doing. Pos- + sible reasons to use this option: + + o Trying to recover data from a corrupt .xz file. + + o Speeding up decompression. This matters mostly with SHA-256 + or with files that have compressed extremely well. It's rec- + ommended to not use this option for this purpose unless the + file integrity is verified externally in some other way. + + -0 ... -9 + Select a compression preset level. The default is -6. If mul- + tiple preset levels are specified, the last one takes effect. + If a custom filter chain was already specified, setting a com- + pression preset level clears the custom filter chain. + + The differences between the presets are more significant than + with gzip(1) and bzip2(1). The selected compression settings + determine the memory requirements of the decompressor, thus us- + ing a too high preset level might make it painful to decompress + the file on an old system with little RAM. Specifically, it's + not a good idea to blindly use -9 for everything like it often + is with gzip(1) and bzip2(1). + + -0 ... -3 + These are somewhat fast presets. -0 is sometimes faster + than gzip -9 while compressing much better. The higher + ones often have speed comparable to bzip2(1) with compa- + rable or better compression ratio, although the results + depend a lot on the type of data being compressed. + + -4 ... -6 + Good to very good compression while keeping decompressor + memory usage reasonable even for old systems. -6 is the + default, which is usually a good choice for distributing + files that need to be decompressible even on systems with + only 16 MiB RAM. (-5e or -6e may be worth considering + too. See --extreme.) + + -7 ... -9 + These are like -6 but with higher compressor and decom- + pressor memory requirements. These are useful only when + compressing files bigger than 8 MiB, 16 MiB, and 32 MiB, + respectively. + + On the same hardware, the decompression speed is approximately a + constant number of bytes of compressed data per second. In + other words, the better the compression, the faster the decom- + pression will usually be. This also means that the amount of + uncompressed output produced per second can vary a lot. + + The following table summarises the features of the presets: + + Preset DictSize CompCPU CompMem DecMem + -0 256 KiB 0 3 MiB 1 MiB + -1 1 MiB 1 9 MiB 2 MiB + -2 2 MiB 2 17 MiB 3 MiB + -3 4 MiB 3 32 MiB 5 MiB + -4 4 MiB 4 48 MiB 5 MiB + -5 8 MiB 5 94 MiB 9 MiB + -6 8 MiB 6 94 MiB 9 MiB + -7 16 MiB 6 186 MiB 17 MiB + -8 32 MiB 6 370 MiB 33 MiB + -9 64 MiB 6 674 MiB 65 MiB + + Column descriptions: + + o DictSize is the LZMA2 dictionary size. It is waste of memory + to use a dictionary bigger than the size of the uncompressed + file. This is why it is good to avoid using the presets -7 + ... -9 when there's no real need for them. At -6 and lower, + the amount of memory wasted is usually low enough to not mat- + ter. + + o CompCPU is a simplified representation of the LZMA2 settings + that affect compression speed. The dictionary size affects + speed too, so while CompCPU is the same for levels -6 ... -9, + higher levels still tend to be a little slower. To get even + slower and thus possibly better compression, see --extreme. + + o CompMem contains the compressor memory requirements in the + single-threaded mode. It may vary slightly between xz ver- + sions. + + o DecMem contains the decompressor memory requirements. That + is, the compression settings determine the memory require- + ments of the decompressor. The exact decompressor memory us- + age is slightly more than the LZMA2 dictionary size, but the + values in the table have been rounded up to the next full + MiB. + + Memory requirements of the multi-threaded mode are significantly + higher than that of the single-threaded mode. With the default + value of --block-size, each thread needs 3*3*DictSize plus Comp- + Mem or DecMem. For example, four threads with preset -6 needs + 660-670 MiB of memory. + + -e, --extreme + Use a slower variant of the selected compression preset level + (-0 ... -9) to hopefully get a little bit better compression ra- + tio, but with bad luck this can also make it worse. Decompres- + sor memory usage is not affected, but compressor memory usage + increases a little at preset levels -0 ... -3. + + Since there are two presets with dictionary sizes 4 MiB and + 8 MiB, the presets -3e and -5e use slightly faster settings + (lower CompCPU) than -4e and -6e, respectively. That way no two + presets are identical. + + Preset DictSize CompCPU CompMem DecMem + -0e 256 KiB 8 4 MiB 1 MiB + -1e 1 MiB 8 13 MiB 2 MiB + -2e 2 MiB 8 25 MiB 3 MiB + -3e 4 MiB 7 48 MiB 5 MiB + -4e 4 MiB 8 48 MiB 5 MiB + -5e 8 MiB 7 94 MiB 9 MiB + -6e 8 MiB 8 94 MiB 9 MiB + -7e 16 MiB 8 186 MiB 17 MiB + -8e 32 MiB 8 370 MiB 33 MiB + + -9e 64 MiB 8 674 MiB 65 MiB + + For example, there are a total of four presets that use 8 MiB + dictionary, whose order from the fastest to the slowest is -5, + -6, -5e, and -6e. + + --fast + --best These are somewhat misleading aliases for -0 and -9, respec- + tively. These are provided only for backwards compatibility + with LZMA Utils. Avoid using these options. + + --block-size=size + When compressing to the .xz format, split the input data into + blocks of size bytes. The blocks are compressed independently + from each other, which helps with multi-threading and makes lim- + ited random-access decompression possible. This option is typi- + cally used to override the default block size in multi-threaded + mode, but this option can be used in single-threaded mode too. + + In multi-threaded mode about three times size bytes will be al- + located in each thread for buffering input and output. The de- + fault size is three times the LZMA2 dictionary size or 1 MiB, + whichever is more. Typically a good value is 2-4 times the size + of the LZMA2 dictionary or at least 1 MiB. Using size less than + the LZMA2 dictionary size is waste of RAM because then the LZMA2 + dictionary buffer will never get fully used. In multi-threaded + mode, the sizes of the blocks are stored in the block headers. + This size information is required for multi-threaded decompres- + sion. + + In single-threaded mode no block splitting is done by default. + Setting this option doesn't affect memory usage. No size infor- + mation is stored in block headers, thus files created in single- + threaded mode won't be identical to files created in multi- + threaded mode. The lack of size information also means that xz + won't be able decompress the files in multi-threaded mode. + + --block-list=items + When compressing to the .xz format, start a new block with an + optional custom filter chain after the given intervals of uncom- + pressed data. + + The items are a comma-separated list. Each item consists of an + optional filter chain number between 0 and 9 followed by a colon + (:) and a required size of uncompressed data. Omitting an item + (two or more consecutive commas) is a shorthand to use the size + and filters of the previous item. + + If the input file is bigger than the sum of the sizes in items, + the last item is repeated until the end of the file. A special + value of 0 may be used as the last size to indicate that the + rest of the file should be encoded as a single block. + + An alternative filter chain for each block can be specified in + combination with the --filters1=filters ... --filters9=filters + options. These options define filter chains with an identifier + between 1-9. Filter chain 0 can be used to refer to the default + filter chain, which is the same as not specifying a filter + chain. The filter chain identifier can be used before the un- + compressed size, followed by a colon (:). For example, if one + specifies --block-list=1:2MiB,3:2MiB,2:4MiB,,2MiB,0:4MiB then + blocks will be created using: + + o The filter chain specified by --filters1 and 2 MiB input + + o The filter chain specified by --filters3 and 2 MiB input + + o The filter chain specified by --filters2 and 4 MiB input + + o The filter chain specified by --filters2 and 4 MiB input + + o The default filter chain and 2 MiB input + + o The default filter chain and 4 MiB input for every block un- + til end of input. + + If one specifies a size that exceeds the encoder's block size + (either the default value in threaded mode or the value speci- + fied with --block-size=size), the encoder will create additional + blocks while keeping the boundaries specified in items. For ex- + ample, if one specifies --block-size=10MiB + --block-list=5MiB,10MiB,8MiB,12MiB,24MiB and the input file is + 80 MiB, one will get 11 blocks: 5, 10, 8, 10, 2, 10, 10, 4, 10, + 10, and 1 MiB. + + In multi-threaded mode the sizes of the blocks are stored in the + block headers. This isn't done in single-threaded mode, so the + encoded output won't be identical to that of the multi-threaded + mode. + + --flush-timeout=timeout + When compressing, if more than timeout milliseconds (a positive + integer) has passed since the previous flush and reading more + input would block, all the pending input data is flushed from + the encoder and made available in the output stream. This can + be useful if xz is used to compress data that is streamed over a + network. Small timeout values make the data available at the + receiving end with a small delay, but large timeout values give + better compression ratio. + + This feature is disabled by default. If this option is speci- + fied more than once, the last one takes effect. The special + timeout value of 0 can be used to explicitly disable this fea- + ture. + + This feature is not available on non-POSIX systems. + + This feature is still experimental. Currently xz is unsuitable + for decompressing the stream in real time due to how xz does + buffering. + + --memlimit-compress=limit + Set a memory usage limit for compression. If this option is + specified multiple times, the last one takes effect. + + If the compression settings exceed the limit, xz will attempt to + adjust the settings downwards so that the limit is no longer ex- + ceeded and display a notice that automatic adjustment was done. + The adjustments are done in this order: reducing the number of + threads, switching to single-threaded mode if even one thread in + multi-threaded mode exceeds the limit, and finally reducing the + LZMA2 dictionary size. + + When compressing with --format=raw or if --no-adjust has been + specified, only the number of threads may be reduced since it + can be done without affecting the compressed output. + + If the limit cannot be met even with the adjustments described + above, an error is displayed and xz will exit with exit status + 1. + + The limit can be specified in multiple ways: + + o The limit can be an absolute value in bytes. Using an inte- + ger suffix like MiB can be useful. Example: --memlimit-com- + press=80MiB + + o The limit can be specified as a percentage of total physical + memory (RAM). This can be useful especially when setting the + XZ_DEFAULTS environment variable in a shell initialization + script that is shared between different computers. That way + the limit is automatically bigger on systems with more mem- + ory. Example: --memlimit-compress=70% + + o The limit can be reset back to its default value by setting + it to 0. This is currently equivalent to setting the limit + to max (no memory usage limit). + + For 32-bit xz there is a special case: if the limit would be + over 4020 MiB, the limit is set to 4020 MiB. On MIPS32 2000 MiB + is used instead. (The values 0 and max aren't affected by this. + A similar feature doesn't exist for decompression.) This can be + helpful when a 32-bit executable has access to 4 GiB address + space (2 GiB on MIPS32) while hopefully doing no harm in other + situations. + + See also the section Memory usage. + + --memlimit-decompress=limit + Set a memory usage limit for decompression. This also affects + the --list mode. If the operation is not possible without ex- + ceeding the limit, xz will display an error and decompressing + the file will fail. See --memlimit-compress=limit for possible + ways to specify the limit. + + --memlimit-mt-decompress=limit + Set a memory usage limit for multi-threaded decompression. This + can only affect the number of threads; this will never make xz + refuse to decompress a file. If limit is too low to allow any + multi-threading, the limit is ignored and xz will continue in + single-threaded mode. Note that if also --memlimit-decompress + is used, it will always apply to both single-threaded and multi- + threaded modes, and so the effective limit for multi-threading + will never be higher than the limit set with --memlimit-decom- + press. + + In contrast to the other memory usage limit options, --mem- + limit-mt-decompress=limit has a system-specific default limit. + xz --info-memory can be used to see the current value. + + This option and its default value exist because without any + limit the threaded decompressor could end up allocating an in- + sane amount of memory with some input files. If the default + limit is too low on your system, feel free to increase the limit + but never set it to a value larger than the amount of usable RAM + as with appropriate input files xz will attempt to use that + amount of memory even with a low number of threads. Running out + of memory or swapping will not improve decompression perfor- + mance. + + See --memlimit-compress=limit for possible ways to specify the + limit. Setting limit to 0 resets the limit to the default sys- + tem-specific value. + + -M limit, --memlimit=limit, --memory=limit + This is equivalent to specifying --memlimit-compress=limit + --memlimit-decompress=limit --memlimit-mt-decompress=limit. + + --no-adjust + Display an error and exit if the memory usage limit cannot be + met without adjusting settings that affect the compressed out- + put. That is, this prevents xz from switching the encoder from + multi-threaded mode to single-threaded mode and from reducing + the LZMA2 dictionary size. Even when this option is used the + number of threads may be reduced to meet the memory usage limit + as that won't affect the compressed output. + + Automatic adjusting is always disabled when creating raw streams + (--format=raw). + + -T threads, --threads=threads + Specify the number of worker threads to use. Setting threads to + a special value 0 makes xz use up to as many threads as the pro- + cessor(s) on the system support. The actual number of threads + can be fewer than threads if the input file is not big enough + for threading with the given settings or if using more threads + would exceed the memory usage limit. + + The single-threaded and multi-threaded compressors produce dif- + ferent output. Single-threaded compressor will give the small- + est file size but only the output from the multi-threaded com- + pressor can be decompressed using multiple threads. Setting + threads to 1 will use the single-threaded mode. Setting threads + to any other value, including 0, will use the multi-threaded + compressor even if the system supports only one hardware thread. + (xz 5.2.x used single-threaded mode in this situation.) + + To use multi-threaded mode with only one thread, set threads to + +1. The + prefix has no effect with values other than 1. A + memory usage limit can still make xz switch to single-threaded + mode unless --no-adjust is used. Support for the + prefix was + added in xz 5.4.0. + + If an automatic number of threads has been requested and no mem- + ory usage limit has been specified, then a system-specific de- + fault soft limit will be used to possibly limit the number of + threads. It is a soft limit in sense that it is ignored if the + number of threads becomes one, thus a soft limit will never stop + xz from compressing or decompressing. This default soft limit + will not make xz switch from multi-threaded mode to single- + threaded mode. The active limits can be seen with xz + --info-memory. + + Currently the only threading method is to split the input into + blocks and compress them independently from each other. The de- + fault block size depends on the compression level and can be + overridden with the --block-size=size option. + + Threaded decompression only works on files that contain multiple + blocks with size information in block headers. All large enough + files compressed in multi-threaded mode meet this condition, but + files compressed in single-threaded mode don't even if + --block-size=size has been used. + + The default value for threads is 0. In xz 5.4.x and older the + default is 1. + + Custom compressor filter chains + A custom filter chain allows specifying the compression settings in de- + tail instead of relying on the settings associated to the presets. + When a custom filter chain is specified, preset options (-0 ... -9 and + --extreme) earlier on the command line are forgotten. If a preset op- + tion is specified after one or more custom filter chain options, the + new preset takes effect and the custom filter chain options specified + earlier are forgotten. + + A filter chain is comparable to piping on the command line. When com- + pressing, the uncompressed input goes to the first filter, whose output + goes to the next filter (if any). The output of the last filter gets + written to the compressed file. The maximum number of filters in the + chain is four, but typically a filter chain has only one or two fil- + ters. + + Many filters have limitations on where they can be in the filter chain: + some filters can work only as the last filter in the chain, some only + as a non-last filter, and some work in any position in the chain. De- + pending on the filter, this limitation is either inherent to the filter + design or exists to prevent security issues. + + A custom filter chain can be specified in two different ways. The op- + tions --filters=filters and --filters1=filters ... --filters9=filters + allow specifying an entire filter chain in one option using the liblzma + filter string syntax. Alternatively, a filter chain can be specified + by using one or more individual filter options in the order they are + wanted in the filter chain. That is, the order of the individual fil- + ter options is significant! When decoding raw streams (--format=raw), + the filter chain must be specified in the same order as it was speci- + fied when compressing. Any individual filter or preset options speci- + fied before the full chain option (--filters=filters) will be forgot- + ten. Individual filters specified after the full chain option will re- + set the filter chain. + + Both the full and individual filter options take filter-specific op- + tions as a comma-separated list. Extra commas in options are ignored. + Every option has a default value, so specify those you want to change. + + To see the whole filter chain and options, use xz -vv (that is, use + --verbose twice). This works also for viewing the filter chain options + used by presets. + + --filters=filters + Specify the full filter chain or a preset in a single option. + Each filter can be separated by spaces or two dashes (--). fil- + ters may need to be quoted on the shell command line so it is + parsed as a single option. To denote options, use : or =. A + preset can be prefixed with a - and followed with zero or more + flags. The only supported flag is e to apply the same options + as --extreme. + + --filters1=filters ... --filters9=filters + Specify up to nine additional filter chains that can be used + with --block-list. + + For example, when compressing an archive with executable files + followed by text files, the executable part could use a filter + chain with a BCJ filter and the text part only the LZMA2 filter. + + --filters-help + Display a help message describing how to specify presets and + custom filter chains in the --filters and --filters1=filters ... + --filters9=filters options, and exit successfully. + + --lzma1[=options] + --lzma2[=options] + Add LZMA1 or LZMA2 filter to the filter chain. These filters + can be used only as the last filter in the chain. + + LZMA1 is a legacy filter, which is supported almost solely due + to the legacy .lzma file format, which supports only LZMA1. + LZMA2 is an updated version of LZMA1 to fix some practical is- + sues of LZMA1. The .xz format uses LZMA2 and doesn't support + LZMA1 at all. Compression speed and ratios of LZMA1 and LZMA2 + are practically the same. + + LZMA1 and LZMA2 share the same set of options: + + preset=preset + Reset all LZMA1 or LZMA2 options to preset. Preset con- + sist of an integer, which may be followed by single-let- + ter preset modifiers. The integer can be from 0 to 9, + matching the command line options -0 ... -9. The only + supported modifier is currently e, which matches --ex- + treme. If no preset is specified, the default values of + LZMA1 or LZMA2 options are taken from the preset 6. + + dict=size + Dictionary (history buffer) size indicates how many bytes + of the recently processed uncompressed data is kept in + memory. The algorithm tries to find repeating byte se- + quences (matches) in the uncompressed data, and replace + them with references to the data currently in the dictio- + nary. The bigger the dictionary, the higher is the + chance to find a match. Thus, increasing dictionary size + usually improves compression ratio, but a dictionary big- + ger than the uncompressed file is waste of memory. + + Typical dictionary size is from 64 KiB to 64 MiB. The + minimum is 4 KiB. The maximum for compression is cur- + rently 1.5 GiB (1536 MiB). The decompressor already sup- + ports dictionaries up to one byte less than 4 GiB, which + is the maximum for the LZMA1 and LZMA2 stream formats. + + Dictionary size and match finder (mf) together determine + the memory usage of the LZMA1 or LZMA2 encoder. The same + (or bigger) dictionary size is required for decompressing + that was used when compressing, thus the memory usage of + the decoder is determined by the dictionary size used + when compressing. The .xz headers store the dictionary + size either as 2^n or 2^n + 2^(n-1), so these sizes are + somewhat preferred for compression. Other sizes will get + rounded up when stored in the .xz headers. + + lc=lc Specify the number of literal context bits. The minimum + is 0 and the maximum is 4; the default is 3. In addi- + tion, the sum of lc and lp must not exceed 4. + + All bytes that cannot be encoded as matches are encoded + as literals. That is, literals are simply 8-bit bytes + that are encoded one at a time. + + The literal coding makes an assumption that the highest + lc bits of the previous uncompressed byte correlate with + the next byte. For example, in typical English text, an + upper-case letter is often followed by a lower-case let- + ter, and a lower-case letter is usually followed by an- + other lower-case letter. In the US-ASCII character set, + the highest three bits are 010 for upper-case letters and + 011 for lower-case letters. When lc is at least 3, the + literal coding can take advantage of this property in the + uncompressed data. + + The default value (3) is usually good. If you want maxi- + mum compression, test lc=4. Sometimes it helps a little, + and sometimes it makes compression worse. If it makes it + worse, test lc=2 too. + + lp=lp Specify the number of literal position bits. The minimum + is 0 and the maximum is 4; the default is 0. + + Lp affects what kind of alignment in the uncompressed + data is assumed when encoding literals. See pb below for + more information about alignment. + + pb=pb Specify the number of position bits. The minimum is 0 + and the maximum is 4; the default is 2. + + Pb affects what kind of alignment in the uncompressed + data is assumed in general. The default means four-byte + alignment (2^pb=2^2=4), which is often a good choice when + there's no better guess. + + When the alignment is known, setting pb accordingly may + reduce the file size a little. For example, with text + files having one-byte alignment (US-ASCII, ISO-8859-*, + UTF-8), setting pb=0 can improve compression slightly. + For UTF-16 text, pb=1 is a good choice. If the alignment + is an odd number like 3 bytes, pb=0 might be the best + choice. + + Even though the assumed alignment can be adjusted with pb + and lp, LZMA1 and LZMA2 still slightly favor 16-byte + alignment. It might be worth taking into account when + designing file formats that are likely to be often com- + pressed with LZMA1 or LZMA2. + + mf=mf Match finder has a major effect on encoder speed, memory + usage, and compression ratio. Usually Hash Chain match + finders are faster than Binary Tree match finders. The + default depends on the preset: 0 uses hc3, 1-3 use hc4, + and the rest use bt4. + + The following match finders are supported. The memory + usage formulas below are rough approximations, which are + closest to the reality when dict is a power of two. + + hc3 Hash Chain with 2- and 3-byte hashing + Minimum value for nice: 3 + Memory usage: + dict * 7.5 (if dict <= 16 MiB); + dict * 5.5 + 64 MiB (if dict > 16 MiB) + + hc4 Hash Chain with 2-, 3-, and 4-byte hashing + Minimum value for nice: 4 + Memory usage: + dict * 7.5 (if dict <= 32 MiB); + dict * 6.5 (if dict > 32 MiB) + + bt2 Binary Tree with 2-byte hashing + Minimum value for nice: 2 + Memory usage: dict * 9.5 + + bt3 Binary Tree with 2- and 3-byte hashing + Minimum value for nice: 3 + Memory usage: + dict * 11.5 (if dict <= 16 MiB); + dict * 9.5 + 64 MiB (if dict > 16 MiB) + + bt4 Binary Tree with 2-, 3-, and 4-byte hashing + Minimum value for nice: 4 + Memory usage: + dict * 11.5 (if dict <= 32 MiB); + dict * 10.5 (if dict > 32 MiB) + + mode=mode + Compression mode specifies the method to analyze the data + produced by the match finder. Supported modes are fast + and normal. The default is fast for presets 0-3 and nor- + mal for presets 4-9. + + Usually fast is used with Hash Chain match finders and + normal with Binary Tree match finders. This is also what + the presets do. + + nice=nice + Specify what is considered to be a nice length for a + match. Once a match of at least nice bytes is found, the + algorithm stops looking for possibly better matches. + + Nice can be 2-273 bytes. Higher values tend to give bet- + ter compression ratio at the expense of speed. The de- + fault depends on the preset. + + depth=depth + Specify the maximum search depth in the match finder. + The default is the special value of 0, which makes the + compressor determine a reasonable depth from mf and nice. + + Reasonable depth for Hash Chains is 4-100 and 16-1000 for + Binary Trees. Using very high values for depth can make + the encoder extremely slow with some files. Avoid set- + ting the depth over 1000 unless you are prepared to in- + terrupt the compression in case it is taking far too + long. + + When decoding raw streams (--format=raw), LZMA2 needs only the + dictionary size. LZMA1 needs also lc, lp, and pb. + + --x86[=options] + --arm[=options] + --armthumb[=options] + --arm64[=options] + --powerpc[=options] + --ia64[=options] + --sparc[=options] + --riscv[=options] + Add a branch/call/jump (BCJ) filter to the filter chain. These + filters can be used only as a non-last filter in the filter + chain. + + A BCJ filter converts relative addresses in the machine code to + their absolute counterparts. This doesn't change the size of + the data but it increases redundancy, which can help LZMA2 to + produce 0-15 % smaller .xz file. The BCJ filters are always re- + versible, so using a BCJ filter for wrong type of data doesn't + cause any data loss, although it may make the compression ratio + slightly worse. The BCJ filters are very fast and use an in- + significant amount of memory. + + These BCJ filters have known problems related to the compression + ratio: + + o Some types of files containing executable code (for example, + object files, static libraries, and Linux kernel modules) + have the addresses in the instructions filled with filler + values. These BCJ filters will still do the address conver- + sion, which will make the compression worse with these files. + + o If a BCJ filter is applied on an archive, it is possible that + it makes the compression ratio worse than not using a BCJ + filter. For example, if there are similar or even identical + executables then filtering will likely make the files less + similar and thus compression is worse. The contents of non- + executable files in the same archive can matter too. In + practice one has to try with and without a BCJ filter to see + which is better in each situation. + + Different instruction sets have different alignment: the exe- + cutable file must be aligned to a multiple of this value in the + input data to make the filter work. + + Filter Alignment Notes + x86 1 32-bit or 64-bit x86 + ARM 4 + ARM-Thumb 2 + ARM64 4 4096-byte alignment is best + + PowerPC 4 Big endian only + IA-64 16 Itanium + SPARC 4 + RISC-V 2 + + Since the BCJ-filtered data is usually compressed with LZMA2, + the compression ratio may be improved slightly if the LZMA2 op- + tions are set to match the alignment of the selected BCJ filter. + Examples: + + o IA-64 filter has 16-byte alignment so pb=4,lp=4,lc=0 is good + with LZMA2 (2^4=16). + + o RISC-V code has 2-byte or 4-byte alignment depending on + whether the file contains 16-bit compressed instructions (the + C extension). When 16-bit instructions are used, + pb=2,lp=1,lc=3 or pb=1,lp=1,lc=3 is good. When 16-bit in- + structions aren't present, pb=2,lp=2,lc=2 is the best. read- + elf -h can be used to check if "RVC" appears on the "Flags" + line. + + o ARM64 is always 4-byte aligned so pb=2,lp=2,lc=2 is the best. + + o The x86 filter is an exception. It's usually good to stick + to LZMA2's defaults (pb=2,lp=0,lc=3) when compressing x86 ex- + ecutables. + + All BCJ filters support the same options: + + start=offset + Specify the start offset that is used when converting be- + tween relative and absolute addresses. The offset must + be a multiple of the alignment of the filter (see the ta- + ble above). The default is zero. In practice, the de- + fault is good; specifying a custom offset is almost never + useful. + + --delta[=options] + Add the Delta filter to the filter chain. The Delta filter can + be only used as a non-last filter in the filter chain. + + Currently only simple byte-wise delta calculation is supported. + It can be useful when compressing, for example, uncompressed + bitmap images or uncompressed PCM audio. However, special pur- + pose algorithms may give significantly better results than Delta + + LZMA2. This is true especially with audio, which compresses + faster and better, for example, with flac(1). + + Supported options: + + dist=distance + Specify the distance of the delta calculation in bytes. + distance must be 1-256. The default is 1. + + For example, with dist=2 and eight-byte input A1 B1 A2 B3 + A3 B5 A4 B7, the output will be A1 B1 01 02 01 02 01 02. + + Other options + -q, --quiet + Suppress warnings and notices. Specify this twice to suppress + errors too. This option has no effect on the exit status. That + is, even if a warning was suppressed, the exit status to indi- + cate a warning is still used. + + -v, --verbose + Be verbose. If standard error is connected to a terminal, xz + will display a progress indicator. Specifying --verbose twice + will give even more verbose output. + + The progress indicator shows the following information: + + o Completion percentage is shown if the size of the input file + is known. That is, the percentage cannot be shown in pipes. + + o Amount of compressed data produced (compressing) or consumed + (decompressing). + + o Amount of uncompressed data consumed (compressing) or pro- + duced (decompressing). + + o Compression ratio, which is calculated by dividing the amount + of compressed data processed so far by the amount of uncom- + pressed data processed so far. + + o Compression or decompression speed. This is measured as the + amount of uncompressed data consumed (compression) or pro- + duced (decompression) per second. It is shown after a few + seconds have passed since xz started processing the file. + + o Elapsed time in the format M:SS or H:MM:SS. + + o Estimated remaining time is shown only when the size of the + input file is known and a couple of seconds have already + passed since xz started processing the file. The time is + shown in a less precise format which never has any colons, + for example, 2 min 30 s. + + When standard error is not a terminal, --verbose will make xz + print the filename, compressed size, uncompressed size, compres- + sion ratio, and possibly also the speed and elapsed time on a + single line to standard error after compressing or decompressing + the file. The speed and elapsed time are included only when the + operation took at least a few seconds. If the operation didn't + finish, for example, due to user interruption, also the comple- + tion percentage is printed if the size of the input file is + known. + + -Q, --no-warn + Don't set the exit status to 2 even if a condition worth a warn- + ing was detected. This option doesn't affect the verbosity + level, thus both --quiet and --no-warn have to be used to not + display warnings and to not alter the exit status. + + --robot + Print messages in a machine-parsable format. This is intended + to ease writing frontends that want to use xz instead of li- + blzma, which may be the case with various scripts. The output + with this option enabled is meant to be stable across xz re- + leases. See the section ROBOT MODE for details. + + --info-memory + Display, in human-readable format, how much physical memory + (RAM) and how many processor threads xz thinks the system has + and the memory usage limits for compression and decompression, + and exit successfully. + + -h, --help + Display a help message describing the most commonly used op- + tions, and exit successfully. + + -H, --long-help + Display a help message describing all features of xz, and exit + successfully + + -V, --version + Display the version number of xz and liblzma in human readable + format. To get machine-parsable output, specify --robot before + --version. + +ROBOT MODE + The robot mode is activated with the --robot option. It makes the out- + put of xz easier to parse by other programs. Currently --robot is sup- + ported only together with --list, --filters-help, --info-memory, and + --version.

The first column of every + line has a string that indicates the type of the information found on + that line: + + name This is always the first line when starting to list a file.

Total amount of physical memory (RAM) in bytes. + + 2. Memory usage limit for compression in bytes (--memlimit-compress). + A special value of 0 indicates the default setting which for sin- + gle-threaded mode is the same as no limit. + + 3. Memory usage limit for decompression in bytes (--memlimit-decom- + press). A special value of 0 indicates the default setting which + for single-threaded mode is the same as no limit. + + 4. Since xz 5.3.4alpha: Memory usage for multi-threaded decompression + in bytes (--memlimit-mt-decompress). This is never zero because a + system-specific default value shown in the column 5 is used if no + limit has been specified explicitly. This is also never greater + than the value in the column 3 even if a larger value has been + specified with --memlimit-mt-decompress. + + 5. Since xz 5.3.4alpha: A system-specific default memory usage limit + that is used to limit the number of threads when compressing with + an automatic number of threads (--threads=0) and no memory usage + limit has been specified (--memlimit-compress). This is also used + as the default value for --memlimit-mt-decompress. + + 6. Since xz 5.3.4alpha: Number of available processor threads. + + In the future, the output of xz --robot --info-memory may have more + columns, but never more than a single line. + + Version + xz --robot --version prints the version number of xz and liblzma in the + following format: + + XZ_VERSION=XYYYZZZS + LIBLZMA_VERSION=XYYYZZZS + + X Major version. + + YYY Minor version. Even numbers are stable. Odd numbers are alpha + or beta versions. + + ZZZ Patch level for stable releases or just a counter for develop- + ment releases. + + S Stability. 0 is alpha, 1 is beta, and 2 is stable. S should be + always 2 when YYY is even. + + XYYYZZZS are the same on both lines if xz and liblzma are from the same + XZ Utils release. + + Examples: 4.999.9beta is 49990091 and 5.0.0 is 50000002. + +EXIT STATUS + 0 All is good. + + 1 An error occurred. + + 2 Something worth a warning occurred, but no actual errors oc- + curred. + + Notices (not warnings or errors) printed on standard error don't affect + the exit status. + +ENVIRONMENT + xz parses space-separated lists of options from the environment vari- + ables XZ_DEFAULTS and XZ_OPT, in this order, before parsing the options + from the command line. Note that only options are parsed from the en- + vironment variables; all non-options are silently ignored. Parsing is + done with getopt_long(3) which is used also for the command line argu- + ments. + + XZ_DEFAULTS + User-specific or system-wide default options. Typically this is + set in a shell initialization script to enable xz's memory usage + limiter by default. Excluding shell initialization scripts and + similar special cases, scripts must never set or unset XZ_DE- + FAULTS. + + XZ_OPT This is for passing options to xz when it is not possible to set + the options directly on the xz command line. This is the case + when xz is run by a script or tool, for example, GNU tar(1): + + XZ_OPT=-2v tar caf foo.tar.xz foo + + Scripts may use XZ_OPT, for example, to set script-specific de- + fault compression options. It is still recommended to allow + users to override XZ_OPT if that is reasonable. For example, in + sh(1) scripts one may use something like this: + + XZ_OPT=${XZ_OPT-"-7e"} + export XZ_OPT + +LZMA UTILS COMPATIBILITY + The command line syntax of xz is practically a superset of lzma, un- + lzma, and lzcat as found from LZMA Utils 4.32.x. In most cases, it is + possible to replace LZMA Utils with XZ Utils without breaking existing + scripts. There are some incompatibilities though, which may sometimes + cause problems. + + Compression preset levels + The numbering of the compression level presets is not identical in xz + and LZMA Utils. The most important difference is how dictionary sizes + are mapped to different presets. Dictionary size is roughly equal to + the decompressor memory usage. + + Level xz LZMA Utils + -0 256 KiB N/A + -1 1 MiB 64 KiB + -2 2 MiB 1 MiB + -3 4 MiB 512 KiB + -4 4 MiB 1 MiB + -5 8 MiB 2 MiB + -6 8 MiB 4 MiB + -7 16 MiB 8 MiB + -8 32 MiB 16 MiB + -9 64 MiB 32 MiB + + The dictionary size differences affect the compressor memory usage too, + but there are some other differences between LZMA Utils and XZ Utils, + which make the difference even bigger: + + Level xz LZMA Utils 4.32.x + -0 3 MiB N/A + -1 9 MiB 2 MiB + -2 17 MiB 12 MiB + -3 32 MiB 12 MiB + -4 48 MiB 16 MiB + -5 94 MiB 26 MiB + -6 94 MiB 45 MiB + -7 186 MiB 83 MiB + -8 370 MiB 159 MiB + -9 674 MiB 311 MiB + + The default preset level in LZMA Utils is -7 while in XZ Utils it is + -6, so both use an 8 MiB dictionary by default. + + Streamed vs. non-streamed .lzma files + The uncompressed size of the file can be stored in the .lzma header. + LZMA Utils does that when compressing regular files. The alternative + is to mark that uncompressed size is unknown and use end-of-payload + marker to indicate where the decompressor should stop. LZMA Utils uses + this method when uncompressed size isn't known, which is the case, for + example, in pipes. + + xz supports decompressing .lzma files with or without end-of-payload + marker, but all .lzma files created by xz will use end-of-payload + marker and have uncompressed size marked as unknown in the .lzma + header. This may be a problem in some uncommon situations. For exam- + ple, a .lzma decompressor in an embedded device might work only with + files that have known uncompressed size. If you hit this problem, you + need to use LZMA Utils or LZMA SDK to create .lzma files with known un- + compressed size. + + Unsupported .lzma files + The .lzma format allows lc values up to 8, and lp values up to 4. LZMA + Utils can decompress files with any lc and lp, but always creates files + with lc=3 and lp=0. Creating files with other lc and lp is possible + with xz and with LZMA SDK. + + The implementation of the LZMA1 filter in liblzma requires that the sum + of lc and lp must not exceed 4. Thus, .lzma files, which exceed this + limitation, cannot be decompressed with xz. + + LZMA Utils creates only .lzma files which have a dictionary size of 2^n + (a power of 2) but accepts files with any dictionary size. liblzma ac- + cepts only .lzma files which have a dictionary size of 2^n or 2^n + + 2^(n-1). This is to decrease false positives when detecting .lzma + files. + + These limitations shouldn't be a problem in practice, since practically + all .lzma files have been compressed with settings that liblzma will + accept. + + Trailing garbage + When decompressing, LZMA Utils silently ignore everything after the + first .lzma stream. In most situations, this is a bug. This also + means that LZMA Utils don't support decompressing concatenated .lzma + files. + + If there is data left after the first .lzma stream, xz considers the + file to be corrupt unless --single-stream was used. This may break ob- + scure scripts which have assumed that trailing garbage is ignored. + +NOTES + Compressed output may vary + The exact compressed output produced from the same uncompressed input + file may vary between XZ Utils versions even if compression options are + identical. This is because the encoder can be improved (faster or bet- + ter compression) without affecting the file format. The output can + vary even between different builds of the same XZ Utils version, if + different build options are used. + + The above means that once --rsyncable has been implemented, the result- + ing files won't necessarily be rsyncable unless both old and new files + have been compressed with the same xz version. This problem can be + fixed if a part of the encoder implementation is frozen to keep rsynca- + ble output stable across xz versions. + + Embedded .xz decompressors + Embedded .xz decompressor implementations like XZ Embedded don't neces- + sarily support files created with integrity check types other than none + and crc32. Since the default is --check=crc64, you must use + --check=none or --check=crc32 when creating files for embedded systems. + + Outside embedded systems, all .xz format decompressors support all the + check types, or at least are able to decompress the file without veri- + fying the integrity check if the particular check is not supported. + + XZ Embedded supports BCJ filters, but only with the default start off- + set. + +EXAMPLES + Basics + Compress the file foo into foo.xz using the default compression level + (-6), and remove foo if compression is successful: + + xz foo + + Decompress bar.xz into bar and don't remove bar.xz even if decompres- + sion is successful: + + xz -dk bar.xz + + Create baz.tar.xz with the preset -4e (-4 --extreme), which is slower + than the default -6, but needs less memory for compression and decom- + pression (48 MiB and 5 MiB, respectively): + + tar cf - baz | xz -4e > baz.tar.xz + + A mix of compressed and uncompressed files can be decompressed to stan- + dard output with a single command: + + xz -dcf a.txt b.txt.xz c.txt d.txt.lzma > abcd.txt + + Parallel compression of many files + On GNU and *BSD, find(1) and xargs(1) can be used to parallelize com- + pression of many files: + + find . -type f \! -name '*.xz' -print0 \ + | xargs -0r -P4 -n16 xz -T1 + + The -P option to xargs(1) sets the number of parallel xz processes. + The best value for the -n option depends on how many files there are to + be compressed. If there are only a couple of files, the value should + probably be 1; with tens of thousands of files, 100 or even more may be + appropriate to reduce the number of xz processes that xargs(1) will + eventually create. + + The option -T1 for xz is there to force it to single-threaded mode, be- + cause xargs(1) is used to control the amount of parallelization. + + Robot mode + Calculate how many bytes have been saved in total after compressing + multiple files: + + xz --robot --list *.xz | awk '/^totals/{print $5-$4}' + + A script may want to know that it is using new enough xz.

This can be useful, because the presets cover only a subset of + the potentially useful combinations of compression settings. + + The CompCPU columns of the tables from the descriptions of the options + -0 ... -9 and --extreme are useful when customizing LZMA2 presets. + Here are the relevant parts collected from those two tables: + + Preset CompCPU + -0 0 + -1 1 + + -2 2 + -3 3 + -4 4 + -5 5 + -6 6 + -5e 7 + -6e 8 + + If you know that a file requires somewhat big dictionary (for example, + 32 MiB) to compress well, but you want to compress it quicker than xz + -8 would do, a preset with a low CompCPU value (for example, 1) can be + modified to use a bigger dictionary: + + xz --lzma2=preset=1,dict=32MiB foo.tar + + With certain files, the above command may be faster than xz -6 while + compressing significantly better. However, it must be emphasized that + only some files benefit from a big dictionary while keeping the CompCPU + value low. The most obvious situation, where a big dictionary can help + a lot, is an archive containing very similar files of at least a few + megabytes each. The dictionary size has to be significantly bigger + than any individual file to allow LZMA2 to take full advantage of the + similarities between consecutive files. + + If very high compressor and decompressor memory usage is fine, and the + file being compressed is at least several hundred megabytes, it may be + useful to use an even bigger dictionary than the 64 MiB that xz -9 + would use: + + xz -vv --lzma2=dict=192MiB big_foo.tar + + Using -vv (--verbose --verbose) like in the above example can be useful + to see the memory requirements of the compressor and decompressor.

The following command uses + -6e (-6 --extreme) as a base and sets the dictionary to only 64 KiB. + The resulting file can be decompressed with XZ Embedded (that's why + there is --check=crc32) using about 100 KiB of memory. + + xz --check=crc32 --lzma2=preset=6e,dict=64KiB foo + + If you want to squeeze out as many bytes as possible, adjusting the + number of literal context bits (lc) and number of position bits (pb) + can sometimes help.

For example, + a source code archive contains mostly US-ASCII text, so something like + the following might give slightly (like 0.1 %) smaller file than xz -6e + (try also without lc=4): + + xz --lzma2=preset=6e,pb=0,lc=4 source_code.tar + + Using another filter together with LZMA2 can improve compression with + certain file types. For example, to compress a x86-32 or x86-64 shared + library using the x86 BCJ filter: + + xz --x86 --lzma2 libfoo.so + + Note that the order of the filter options is significant. If --x86 is + specified after --lzma2, xz will give an error, because there cannot be + any filter after LZMA2, and also because the x86 BCJ filter cannot be + used as the last filter in the chain. + + The Delta filter together with LZMA2 can give good results with bitmap + images. It should usually beat PNG, which has a few more advanced fil- + ters than simple delta but uses Deflate for the actual compression. + + The image has to be saved in uncompressed format, for example, as un- + compressed TIFF. The distance parameter of the Delta filter is set to + match the number of bytes per pixel in the image. For example, 24-bit + RGB bitmap needs dist=3, and it is also good to pass pb=0 to LZMA2 to + accommodate the three-byte alignment: + + xz --delta=dist=3 --lzma2=pb=0 foo.tiff + + If multiple images have been put into a single archive (for example, + .tar), the Delta filter will work on that too as long as all images + have the same number of bytes per pixel. + +SEE ALSO + xzdec(1), xzdiff(1), xzgrep(1), xzless(1), xzmore(1), gzip(1), + bzip2(1), 7z(1) + + XZ Utils: <https://xz.tukaani.org/xz-utils/> + XZ Embedded: <https://xz.tukaani.org/xz-embedded/> + LZMA SDK: <https://7-zip.org/sdk.html> + + + +Tukaani 2024-02-25 XZ(1) diff --git a/doc/man/txt/xzdec.txt b/doc/man/txt/xzdec.txt new file mode 100644 index 00000000..26bacd8a --- /dev/null +++ b/doc/man/txt/xzdec.txt @@ -0,0 +1,80 @@ +XZDEC(1) XZ Utils XZDEC(1) + + + +NAME + xzdec, lzmadec - Small .xz and .lzma decompressors + +SYNOPSIS + xzdec [option...] [file...] + lzmadec [option...] [file...] + +DESCRIPTION + xzdec is a liblzma-based decompression-only tool for .xz (and only .xz) + files. xzdec is intended to work as a drop-in replacement for xz(1) in + the most common situations where a script has been written to use xz + --decompress --stdout (and possibly a few other commonly used options) + to decompress .xz files. lzmadec is identical to xzdec except that lz- + madec supports .lzma files instead of .xz files. + + To reduce the size of the executable, xzdec doesn't support multi- + threading or localization, and doesn't read options from XZ_DEFAULTS + and XZ_OPT environment variables. xzdec doesn't support displaying in- + termediate progress information: sending SIGINFO to xzdec does nothing, + but sending SIGUSR1 terminates the process instead of displaying + progress information. + +OPTIONS + -d, --decompress, --uncompress + Ignored for xz(1) compatibility. xzdec supports only decompres- + sion. + + -k, --keep + Ignored for xz(1) compatibility. xzdec never creates or removes + any files. + + -c, --stdout, --to-stdout + Ignored for xz(1) compatibility. xzdec always writes the decom- + pressed data to standard output. + + -q, --quiet + Specifying this once does nothing since xzdec never displays any + warnings or notices.
