how do i change my username
so i just installed artix and choosed a username that i regretted immediately. how do i change it?
i tried to change my username by using usermod -l <old username> <new username>
and
usermod -d /home/<new username> -m -g <old username> -l <new username> <old username>
but they threw this error at me. both of them.
usermod: user <username> is currently used by process 1339
i know that i need to be logged in as another user (probably root) but i dont know how to do that. and i know i need to have a all processes relating to my old username terminated. but again. i dont know how to do that. also the arch wiki said something about a "tty" but i dont know how to use/what it is either.
any help appreciated
