I wrote a script that wraps a bunch of system info commands in a more human friendly/readable output. You can get a feel for how the system is operating at a glance or offering system specs when asking for help without the need for additional packages or running tons of commands.
It’s not amazing but it should work on a variety of systems, suggestions for improvements are welcome.

If you want a tiny bit of color in the output then pass it -c but it’s not default because I like to pipe it into less for easier reading and the colour codes aren’t interpreted.

. I will try it today.
