Run a program as a different user

1 Why switch user?
Sometimes, you will want to run a program user root. Some programs will only run if you are user root. Switching user enables you to log in as a normal, under-privileged user and run a particular program as root.

2 Running a GUI program as user root
Some desktops have gksuexec
accessible from a menu. Alternatively, you can use the gksu
command directly from the commandline in a terminal window. You will need to enter user root's password. The program (and only that program) will run as root. When the program is closed, you also exit from root automatically.
2.1 Gnome
- Applications -> System Tools -> Run as different user
- Run: (name of program)
- As user: root
- OK
(Requires gnomesu to be installed)
2.2 KDE
- KDE Main Menu -> Run as different user
- Run: (name of program)
- As user: root
- OK
(Requires kdesu to be installed)
2.3 X Desktop without a menu (generic)
Issue the gksu
command from a terminal window.
$ gksu name of program
3 Running a commandline program as user root
Issue the su
command to switch user to root
$ su password: (enter root password here) # name of program
When you have finished, close the program, then exit from user root at the commandline.
# exit $
