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 speci-
       fied 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 pro-
       gram 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).
