Found in this conversation:
- command-line bootcamp “a tutorial that teaches you how to work at the command-line. You’ll learn all the basic skills needed to start being productive in the UNIX terminal.”
- bashcrawl “Learn Linux commands by playing a simple text adventure.”
Also in that thread:
I’d definitely recommend Ryan’s Tutorials for learning how to script, and Bandit for learning navigation and Linux in general.
These two helped me a lot to find my way through UNIX.
Ryan’s Tutorials has line by line explanation and for Bandit, there’s a lot of walk-throughs on how to proceed.
