A quick bash/zsh tip

Tags: linux, bash

Here's a quick tip to improve your bash/zsh life.

! is a valid character you can use in an alias. I use it to mark aliases which run under sudo, for example on my Debian box I have:

alias e!="sudo ${EDITOR}"
alias a!="sudo apt"
alias s!="sudo systemctl"
alias in!="sudo apt install"

As a bonus, ! doesn't seem to be used in the names of any other commands I have installed. I can't remember ever seeing a command with ! in its name, so you should be safe with this. If I'm wrong, please put me right on Mastodon!

That's it. That's the post. I usually write longer things, but I posted this tip on Mastodon and people seemed to like it, so it should also exist here.
