mboelen, 
I'm working on a cheat sheet for #AWK. This nifty tool is easily overlooked, but so powerful that it really made me invest more time into learning it.
The initial version of the cheat sheet is available and ready for feedback: https://linux-audit.com/cheat-sheets/awk/
Boosts would be appreciated, and feedback even more!
What are your AWK one-liners that others really need to know and should be included?
Special thanks to @DopeGhoti
