I’ll try my best to answer any questions here, but I hope others in the community will contribute too!

    This is 80% of my usage of awk and sed:

    “ugh, I need the 4th column of this print out”: command | awk '{print $4}'

    Useful for getting pids out of a ps command you applied a bunch of greps to.

    ”hm, if I change all ‘this’ to ‘that’ in the print out, I get what I want": command | sed "s/this/that/g"

    Useful for a lot of things, like “I need to change the urls in this to that” or whatever.

    Basically the rest I have to look up.
