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),  or  bzip2(1).   All  options
       specified are passed directly to grep(1).

       If  no  file  is  specified, then the standard input is decompressed if
       necessary and fed  to  grep(1).   When  reading  from  standard  input,
       gzip(1) and bzip2(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), zgrep(1)
