There are many more useful options that I didn't mention here.Grep - rl "search-string" / path/ to/ serch/ dir This knowledge should be sufficient to get you started and be productive. Linux shell, how to use the exec option in find with examples.To learn more about -exec, here are some resources to get started: This searches for all results containing "model.rb" in their path's last component, run grep quietly ( -q) to look for lines containing "to_hash" string, then cat these files. name "*model.rb" -exec grep -q to_hash " "
