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).
