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.
