Well, grep is certainly the best way to search through a file... combined with options that allow you to only display the name of the files that contain the search string, it'd be hard to duplicate.

You should be able to search an entire filesystem using a string like this:
Code:
find . -type f -print | xargs grep -l "search string" 2>/dev/null

The "file" command will skip directories, the "-l" option to grep will only tell you which files the string is in, and the "2>/dev/null" will send any errors (as a result of something like trying to grep a file that you don't own, or don't have permissions to look at) to the null device - a suitable place for them!

NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
gzgrep is used to invoke the grep on compress'ed or gzip'ed 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 gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep gzgrep string files for csh: (setenv GREP fgrep; gzgrep string files) AUTHOR
