Quick tip: If you are ever in a situation where you want to search for a keyword in every file of a directory (or even the entire computer), a very useful command line tool is grep (manual), which print lines of any file names, or any lines of text inside a file, that matches a defined pattern. Sample usage is as follows:

grep -rnw '/path/to/somewhere/' -e 'word pattern'

where

  • -r or -R is recursive search
  • -n is show line number of matches
  • -w is find match for the whole word
  • -e is the word pattern you’d like to search
