zgrep(1) 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).
