"Since this is just a reverse version of cat, I called the program recat."

Curious if you compared the end result with "tac".

• awk-hack-the-planet

  5 230 3.8 Ruby

  Source code repo for Ben Porter (FreedomBen)'s free course on Awk (originally a talk at Linux Fest Northwest 2019 and 2020)

Kind of a shameless plug, but you mentioned wanting to get better at Awk. I had that same desire and created a small course based on what I learned. The course got great feedback.

There is a video presentation, and a set of "challenges" you can use to incrementally get more complex with awk, starting from super simple.

The challenges repo is on github here: https://github.com/FreedomBen/awk-hack-the-planet

If you want to watch the videos, there are links in the github repo but for convenience:

>Awk and sed are more of the UNIX magic that I have always thought was really cool, though I never really understood what they were used for.

I was so put off by their syntax that I didn't even bother to try to learn them when I was a newbie. If I had a time machine, I would certainly go back and tell myself to learn these tools and save plenty of time instead of always using vim/perl for every text processing problem. I've now written my own books (https://github.com/learnbyexample/scripting_course#ebooks) - might help you.

For `bash`, I'd highly recommend these resources:
