Useful Bash functions - part 3

Overview

This is the third show about Bash functions. These are a little more advanced than in the earlier shows, and I thought I'd share them in case they are useful to anyone.

As before it would be interesting to receive feedback on these functions and would be great if other Bash users contributed ideas of their own.
