Bash Scripts

Simple Bash scripts to improve the CLI experience. Primarily developed for Ubuntu 22.04 but likely compatible with other Debian distros.

You should never trust scripts you aren't familiar with. Piping straight to bash is unsafe.

tl;dr: You probably shouldn't use these scripts unless you wrote them yourself.
