Here’s another UNIX utility, but this one is also for people that thought Terminal stuff wasn’t for them. CLIX (“Command Line Interface for Mac OS X”) is a GUI front end for UNIX commands. It comes with over 1000 commands so you can perform many tasks that are only available through the Terminal. For example, you can delete the browser history of all your browsers with just one command.
Advanced users can modify or write their own commands and save them as libraries of commands. Then just double click a task to run it.
