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), 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.

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

SEE ALSO

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