Yup, I agree.

It looks like ffmpeg is using about 1/3 of the processing power, but this is likely intentional, because if it froze your computer you’d be pissed.

Heres a good response on SO: https://unix.stackexchange.com/questions/223432/in-zsh-how-can-i-more-quickly-disown-the-foreground-process/223433#223433

Having a global keybind to disown the foreground process is impossible: Keystrokes are received by the foreground process, not by the shell. You need to first suspend it with Ctrl+z if you want to disown it.

However, turns out there’s a zsh option to speed up disowning then continuing: With setopt AUTO_CONTINUE, disown will automatically also send SIGCONT.

So you can get it down to C-z disown.

Most screenshot tools allow you to pass a name as an argument, so you could make a shell script to generate the name you want then call the screenshotting tool with the appropriate name. Also, consider using flameshot

Using readlink -f instead of cd && pwd, and /../ instead of multiple dirnames will make it a lot more readable:
export DOT="$(readlink -f "$(dirname "${BASH_SOURCE[0]:-${(%):-%x}}")"/../../)"

You’re doing a lot of confusing and unnecessary stuff here so it’s hard to understand what you want, but I think this is what you’re trying to do:

source "$(dirname ${BASH_SOURCE[0]})"/../config/zsh/.zshenv

return just exits from the function it is directly inside of. I think you just want to put if command -v pacstall; then in the last function.

Also, you should be able to tell it doesn’t work by running it =/

I think this is as close as you’re going to get
xargs apt-get install --ignore-missing < my_package_list.txt
