       xzgrep - search compressed files for a regular expression

       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

       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 neces-
       sary 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

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

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