Shell Functions and Path Variables, Part 3
UNIX can present a bewildering array of tools and techniques, and it's almost impossible for any individual to be intimately familiar with all of them. In my experience, the best developers carry around a large bag of simple but useful techniques and are able to combine them rapidly into a working solution. You don't need to know every detail of every tool to do useful work, but you do need a bag of tricks you understand.
Please feel free to use any of the ideas I've described in this series. You can get a hold of the source code to the shell functions from www.netspinner.co.uk/Downloads/pathfunc.tgz. Let me know if you find any bugs, would like a new feature added, or make an improvement.
