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 suffix supported by xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), or lz4(1) will  be  decom‐
       pressed; 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 decompressed.  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 compatibility with LZMA Utils.  They	 are  depre‐
       cated and will be removed in a future 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 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.
