Topic: The Linux Shell Manual that would have saved me so much time...
Just thought I'd post this for all those out there that are new to the Linux environment, especially command line interface.
I first started trying to learn this stuff about 2 years ago because a lot of products I work on at work use embedded linux and I didn't like just blindly copy/pasting commands when I didn't know what they were doing. If I knew about this page then it would have saved me so much time. After skimming it I'm finding stuff I didn't know too so even if you're somewhat "established" in Linux you may want to give it a read.
PS Note that this is a general guide and not Chumby specific but it should all apply.
