ZGREP(1) User Commands ZGREP(1)
zgrep - search possibly compressed files for a regular expression
zgrep [ grep_options ] [ -e ] pattern filename...
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 is 0 for a match, 1 for no matches, and 2 if trouble.
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).
