xzgrep(1)


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
