On: More Things I Wish I’d Known About Bash

[gdavisson]

I'd recommend against the Advanced Bash-Scripting Guide -- it uses a lot of bad practices (like unquoted variable references!) that you're better off not learning. Instead, check out http://mywiki.wooledge.org/BashGuide and http://mywiki.wooledge.org/BashFAQ. Also, http://www.shellcheck.net is a good automated tool for sanity-checking syntax errors and common mistakes.
