Basic shell skills (Rob Graham)
Rob Graham drops a serious brain dump of command line (bash) kung fu in this lengthy post. Not just what to do, but why. I learned a lot of this in my days of FreeBSD administration, but several of these are newer tools and capabilities(we didn’t do a lot of JSON parsing back then–XML was the new hotness).
Why I like it: I love basics. This is a box set of greatest hits from the basics of system administration and general bash skills.
Bonus: “There’s no wrong answer as to which editor to use, unless that answer is ‘emacs’.”
