zgrep(1) zgrep(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
The zgrep command invokes grep on compressed or gzipped files. All
options specified are passed directly to grep. If no file is speci-
fied, 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).
