How to enable a system-wide function for users including sudo?

Question

I want to make a global alias for killprocessatport so I put at the end in /etc/bash.bashrc

fuserfunction() {
    fuser -KILL -k -n tcp         


        

Answer 1

You can't use an alias or a function in this case. Create an executable script in a location that's on your PATH (as configured by sudo, if your /etc/suoders modifies root's PATH).

#!/bin/sh
exec fuser -KILL -k -n tcp "$@"

Save the script, then set its permissions with chmod +x.
