CentOS

Is it possibel to change the user on command line? Or do I have to logout from GUI and login from GUI, in centos 5.7.

You can use the [b]su[/b] command to switch to a different user:

[code]$ su - newusername[/code]

You will then be prompted for the other user's password.

You can type [b]exit[/b] when you are done to switch back.

That will not switch to the other users desktop.

You have to exit from the desktop to do that switching
