I wrote a book on GNU awk one-liners: https://learnbyexample.github.io/learn_gnuawk/

There's plenty of examples and exercises, plus an entire chapter dedicated to regular expressions.

On mobile; pardon the link format.

In an afternoon, you can learn enough to be more than dangerous.

The presenter drafted up a set of (easy, yet practical) companion exercises and a pt2 video with his own answers. I cannot recommend this talk enough.

Although I hadn't the opportunity to put the knowledge to use and have since forgotten it (i don't work in tech), i find comfort in knowing i can reacquire the power of awk even sooner than the already-short first time around.

GNU AWK User's Guide is reasonably succinct, while being fairly comprehensive.

https://www.gnu.org/software/gawk/manual/gawk.html

The manpage alone is quite useful, though lacks some useful details.

The awk FAQ provides general background, including diffeerences between implementations:

You can use the notes of Bruce Barnett for quick lookups:
