XZGREP(1)                          XZ Utils                          XZGREP(1)



NAME
       xzgrep - search compressed files for a regular expression

SYNOPSIS
       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

DESCRIPTION
       xzgrep invokes grep(1) on files which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or
       bzip2(1).  All options specified are passed directly to grep(1).

       If no file is specified, then the standard input is decompressed if necessary and fed to grep(1).  When reading
       from standard input, gzip(1) and bzip2(1) compressed files are not supported.

       If  xzgrep  is  invoked  as  xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1).  The same
       applies to names lzgrep, lzegrep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.


ENVIRONMENT
       GREP   If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO
       grep(1), xz(1), gzip(1), bzip2(1), zgrep(1)
