## 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)](https://www.chedong.com/phpMan.php/man/grep/1/markdown)  on _files_ which may be either uncompressed or compressed with [**xz**(1)](https://www.chedong.com/phpMan.php/man/xz/1/markdown),
       [**lzma**(1)](https://www.chedong.com/phpMan.php/man/lzma/1/markdown), [**gzip**(1)](https://www.chedong.com/phpMan.php/man/gzip/1/markdown), [**bzip2**(1)](https://www.chedong.com/phpMan.php/man/bzip2/1/markdown), [**lzop**(1)](https://www.chedong.com/phpMan.php/man/lzop/1/markdown), or [**zstd**(1)](https://www.chedong.com/phpMan.php/man/zstd/1/markdown).  All options specified are  passed  directly
       to [**grep**(1)](https://www.chedong.com/phpMan.php/man/grep/1/markdown).

       If no _file_ is specified, then standard input is decompressed if necessary and fed to [**grep**(1)](https://www.chedong.com/phpMan.php/man/grep/1/markdown).
       When reading from standard input, [**gzip**(1)](https://www.chedong.com/phpMan.php/man/gzip/1/markdown), [**bzip2**(1)](https://www.chedong.com/phpMan.php/man/bzip2/1/markdown), [**lzop**(1)](https://www.chedong.com/phpMan.php/man/lzop/1/markdown), and  [**zstd**(1)](https://www.chedong.com/phpMan.php/man/zstd/1/markdown)  compressed  files
       are not supported.

       If  **xzgrep**  is  invoked  as  **xzegrep**  or **xzfgrep** then [**egrep**(1)](https://www.chedong.com/phpMan.php/man/egrep/1/markdown) or [**fgrep**(1)](https://www.chedong.com/phpMan.php/man/fgrep/1/markdown) is used instead of
       [**grep**(1)](https://www.chedong.com/phpMan.php/man/grep/1/markdown).  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)](https://www.chedong.com/phpMan.php/man/grep/1/markdown), [**egrep**(1)](https://www.chedong.com/phpMan.php/man/egrep/1/markdown),
              or [**fgrep**(1)](https://www.chedong.com/phpMan.php/man/fgrep/1/markdown).
