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.

Why didn’t I find this a long time ago? Makes searching through compressed web logs a piece of cake!

Yep… I find zgrep and zcat very useful when running through backup log files.
