NAME

6       xzgrep - search compressed files for a regular expression

SYNOPSIS

9       xzgrep [grep_options] [-e] pattern file...
10       xzegrep ...
11       xzfgrep ...
12       lzgrep ...
13       lzegrep ...
14       lzfgrep ...

DESCRIPTION

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 the standard input is decompressed if
22       necessary and fed  to  grep(1).   When  reading  from  standard  input,
23       gzip(1) and 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.

ENVIRONMENT

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