XZGREP(1)                                    XZ Utils                                   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
       grep(1), xz(1), gzip(1), bzip2(1), lzop(1), zgrep(1)
