Did you ever want to effortlessly start a process with highest (negative) priority?
Like here, where I don’t want the high CPU load of other processes on my system degrade my developing experience (i.e. zippy nvim):
supanice nvim
Here is the shell function accomplishing this:
function supanice {
sudo --preserve-env=PATH nice -n -20 su -c $@ `whoami`
}
