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.
