+NAME
+ xzgrep - search possibly-compressed files for patterns
+
+SYNOPSIS
+ xzgrep [option...] [pattern_list] [file...]
+ xzegrep ...
+ xzfgrep ...
+ lzgrep ...
+ lzegrep ...
+ lzfgrep ...
+
+DESCRIPTION
+ xzgrep invokes grep(1) on uncompressed contents of files. The formats
+ of the files are determined from the filename suffixes. Any file with
+ a suffix supported by xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), or
+ lz4(1) will be decompressed; all other files are assumed to be uncom-
+ pressed.
+
+ If no files are specified or file is - then standard input is read.
+ When reading from standard input, only files supported by xz(1) are de-
+ compressed. Other files are assumed to be in uncompressed form al-
+ ready.
+
+ Most options of grep(1) are supported. However, the following options
+ are not supported:
+
+ -r, --recursive
+
+ -R, --dereference-recursive
+
+ -d, --directories=action
+
+ -Z, --null
+
+ -z, --null-data
+
+ --include=glob
+
+ --exclude=glob
+
+ --exclude-from=file
+
+ --exclude-dir=glob
+
+ xzegrep is an alias for xzgrep -E. xzfgrep is an alias for xzgrep -F.
+
+ The commands lzgrep, lzegrep, and lzfgrep are provided for backward
+ compatibility with LZMA Utils.
+
+EXIT STATUS
+ 0 At least one match was found from at least one of the input
+ files. No errors occurred.
+
+ 1 No matches were found from any of the input files. No errors
+ occurred.
+
+ >1 One or more errors occurred. It is unknown if matches were
+ found.
+
+ENVIRONMENT
+ GREP If GREP is set to a non-empty value, it is used instead of grep,
+ grep -E, or grep -F.
