CLIX: Use UNIX to run over 1,000 maintenance tasks
If you've never used Terminal to execute commands and perform tasks on your Mac, then CLIX is a good starting point. CLIX provides over 1,000 system commands for investigating your system status, cleaning out junk files, accessing hidden Dock settings, and other tweaks related to Finder, Spotlight, Dashboard, Exposé, and many more. The advantage of this is that it's quick, requires no third-party application, and there's no danger of crashes.
In reality, though, CLIX can be a little tricky to master. If you're used to a GUI for administering your maintenance programs and have never used Terminal, then you might find yourself a bit lost. This is particularly true if you've never used the 'Sudo' command, which some commands require before executing.
