XZGREP(1)                           XZ Utils                           XZGREP(1)

NAME
     xzgrep - search possibly-compressed files for patterns

SYNOPSIS
     xzgrep [option...]  [pattern_list] [file...]
     xzegrep ...
     xzfgrep ...
     lzgrep ...  (DEPRECATED)
     lzegrep ...  (DEPRECATED)
     lzfgrep ...  (DEPRECATED)

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  suf-
     fix 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 uncompressed.

     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  decom-
     pressed.  Other files are assumed to be in uncompressed form already.

     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 compat-
     ibility with LZMA Utils.  They are deprecated and will be removed in a  fu-
     ture version.

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  oc-
            curred.

     >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.
