HOW TO : List files that don't contain a string using find and grep

If you run into a situation, where you need to search through a bunch of files and print the names of the files that don’t contain a particular string, here is how you do it in Linux

[code]find -name PATTERN_FOR_FILE_NAMES | xargs grep -L STRING_YOU_ARE_SEARCHING_FOR [/code]

The -L option for grep does this (according to the manual)

Suppress normal output; instead print the name of each input file from which no output would normally have been printed.  The scanning will stop on the first match.
