I'm looking for a efficient method to monitor a local directory in OSX and if any files have been changed in that directory run a bash script to commit the files to github.

Any recommend tools for monitoring a directory for file changes, then triggering an action, i.e. a bash script?

Answer

Using fswatch from your repository:

fswatch . 'git commit -avm "snapshot at ${date}"'

This simple example would only catch changes to files already in the repository.
