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.

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).
