16DESCRIPTION
17       xzgrep  invokes  grep(1)  on  files which may be either uncompressed or
18       compressed with xz(1), lzma(1),  gzip(1),  or  bzip2(1).   All  options
19       specified are passed directly to grep(1).
20
21       If  no file is specified, then standard input is decompressed if neces-
22       sary and fed to grep(1).  When reading from standard input, gzip(1) and
23       bzip2(1) compressed files are not supported.
24
25       If xzgrep is invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is
26       used instead of grep(1).  The same applies to  names  lzgrep,  lzegrep,
27       and  lzfgrep,  which  are provided for backward compatibility with LZMA
28       Utils.

32              of grep(1), egrep(1), or fgrep(1).
