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).
