Changing login user name

I want to change my login name.  I have Mandrake-Linux.  Can
I use 'usermod' to change it, or is there a better safer root?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This should be VERY easy.

Just crack open /etc/passwd and change the line that is your username. for example if your username was nick and you wanted to change it to joe you would find the line that looks like this


And change it to look like this.


You could do this with vi or any text editor if you had root permission. Remember that file permissions are number based, so all of you file permissions will change to the new user name.
