Is there a shorter way to change username, home directory and move files at the same time

Question

I wanted to use and have tried

sudo usermod durrantm_test -mdl durrantm_test2

but I get

Usage: usermod [options] LOGIN
...

However

sudo usermod durrantm_test -l durrantm_test2 -md durrantm_test2

doesn't give an error but seems repetitive, can I shorten it?

Answer 1

usrmodx() { sudo usermod "$1" -l "$2" -md "$2"; }
usrmodx durrantm_test durrantm_test2

But shouldn't it be,

sudo usermod -l new_name -md new_dir old_name

so

sudo usermod -l durrantm_test2 -md durrantm_test2 durrantm_test

and as a function,

moveuser() { sudo usermod -l "$2" -md "$2" "$1"; }
moveuser durrantm_test durrantm_test2

or am I missing something?

This assumes you're using a shell which supports functions (e.g. bash), and avoids aliases because you can't use positional variables.
