Utility to count the number of lines of code in Python or Bash

advertisements

Is there a quick and dirty way in either python or bash script, that can recursively descend a directory and count the total number of lines of code? We would like to be able to exclude certain directories though.

For example:

start at: /apps/projects/reallycoolapp
exclude: lib/, frameworks/

The excluded directories should be recursive as well. For example:

/app/projects/reallycool/lib SHOULD BE EXCLUDED
/app/projects/reallycool/modules/apple/frameworks SHOULD ALSO BE EXCLUDED

This would be a really useful utility.


Found an awesome utility CLOC. https://github.com/AlDanial/cloc

Here is the command we ran:

perl cloc.pl /apps/projects/reallycoolapp --exclude-dir=lib,frameworks

And here is the output
