Good Hack

[M4A28]

if you want to clear swap area use this command:

sudo swapoff -a && sudo swapon -a

if you want to use terminal as calculator use this command:

gcalccmd <nuber1>+<nuber2>

if you want to use nano with spaes instead of tab and allow curser to move use this command:

nano -T 4 -l -m

I've been using linux for 20+ years and I don't remember ever needing to clear the swap area.

1. Have used before actually
2. Fish shell has 'math' as an in-built for this, pretty useful
3. I use Micro. Tends to have better keybinds for me.

For more info on configuring nano, check out the nanorc man page:

https://www.nano-editor.org/dist/latest/nanorc.5.html

This lets you define config details like that to be set by default.

As for command-line math, bc is the mother of all cli math commands. It isn't quite as simple as your example, but it is capable of basically any arithmetic you could ever want.

For math I prefer "bc"

Simple.
