+.SH NAME

+.SH SYNOPSIS

+.I pattern
+.IR filename ".\|.\|."

+.SH DESCRIPTION
+.B  xzgrep
+is used to invoke the
+.BR grep (1)
+on .xz or .lzma compressed files. All options specified are passed directly to
+.BR grep .
+If no file is specified, then the standard input is decompressed
+if necessary and fed to grep.
+Otherwise the given files are uncompressed if necessary and fed to
+.BR grep .
+.PP
+If
+.B xzgrep
+is invoked as
+.B xzegrep
+or
+.B xzfgrep
+then
+.B egrep
+or
+.B fgrep
+is used instead of
+.B grep.
+The same applies to names
+.BR lzgrep ,
+.BR lzegrep ,
+and
+.BR lzfgrep ,
+which are provided for backward compatibility with LZMA Utils.
+
+If the GREP environment variable is set,
+.B xzgrep
+uses it as the
+.B grep
+program to be invoked. For example:
+
+    for sh:  GREP=fgrep  xzgrep string files
+    for csh: (setenv GREP fgrep; xzgrep string files)
