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), or lzop(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), and lzop(1) compressed  files  are
     not supported.

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

ENVIRONMENT

     GREP If the GREP environment variable is set, xzgrep uses it
          instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO

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