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.  These grep options will cause zgrep to terminate with
       an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).   All  other  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 CODE

       2 - An option that is not supported was specified.
