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 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.
