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.
