ZGREP(1)                    General Commands Manual                   ZGREP(1)



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).
