[ZGREP(1)]                    General Commands Manual                   [ZGREP(1)]



**NAME**
       zgrep - search possibly compressed files for a regular expression

**SYNOPSIS**
       **zgrep** [ grep_options ] **[** **-e** **]** _pattern_ _filename_...

**DESCRIPTION**
       _Zgrep_  invokes _grep_ on compressed or gzipped files.  All options speci-
       fied are passed directly to _grep_.  If no file is  specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise
       the given files are uncompressed if necessary and fed to _grep_.

       If the GREP environment variable is set, _zgrep_ uses it as the _grep_ pro-
       gram to be invoked.

**EXIT** **STATUS**
       Exit status is 0 for a match, 1 for no matches, and 2 if trouble.

**BUGS**
       The  following  _grep_ options are not supported: **--dereference-recursive**
       (**-R**), **--directories**  (**-d**),  **--exclude**,  **--exclude-from**,  **--exclude-dir**,
       **--include**, **--null** (**-Z**), **--null-data** (**-z**), and **--recursive** (**-r**).
