Thanks for all the feedback! I’m much happier with it now, and I’ll probably continue to make small changes over time.

I added more detail to the description and made a more relevant example. (I think)

I updated various examples, and replaced <file extension> with <text> in most places and removed it from the legend.

I made this just as much for me as I did for others. Writing things down myself really helps me memorize them.

I added more information to the installing software section, updated section title to specify Arch Linux, and added another section for Debian and Derivatives.

I updated “Log out” to “Exit (sends a signal indicating the end of a text stream)”. Which I think is a lot more accurate, and still easy to understand.
