xzgrep(1)                           XZ Utils                           xzgrep(1)


       xzgrep - search compressed files for a regular expression


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


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

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

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


       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

       >1     One or more errors occurred.  It is unknown if matches were found.


       GREP   If the GREP environment variable is set, xzgrep uses it instead of
              grep(1), grep -E, or grep -F.


       grep(1), xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), zgrep(1)
