The following pages contain step-by-step instructions for searching CHILDES files using BBEdit Lite. The final page contains a (growing) list of suggestions for how to use 'grep' to search for exactly the information that you need. Any additional suggestions are greatly appreciated -- please email them to colin@udel.edu.

  1. Searching multiple files for a simple letter string
  2. Narrowing your search: using the results of a previous search
  3. Narrowing your search: searching for complex patterns using 'grep'
  4. More tips on using grep


Technical tip: if you are using 'grep' to search a file using BBEdit it is a good idea to first run the 'zap gremlins' command on your file(s) before running your search. The effect of this is to remove any null characters -- or other strange animals -- from your files. If these characters are not removed, then you may find that 'grep' terminates before searching your entire file. [Thanks to Carson Schutze (UCLA) for contributing this suggestion.]
