NAME
       zgrep - search possibly compressed files for a regular expression

SYNOPSIS
       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION
       The  zgrep  command  invokes grep on compressed or gzipped files.  All options specified 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 program 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).
