KDE su is a graphical front end for the UNIX® su command for the K
Desktop Environment. It allows you to run a program as different user
by supplying the password for that user. KDE su is an unprivileged
program; it uses the system’s su.
KDE su has one additional feature: it can optionally remember passwords
for you. If you are using this feature, you only need to enter the
password once for each command.
This program is meant to be started from the command line or from
This specifies the program to run as root. It has to be passed
in one argument. So if, for example, you want to start a new
file manager, you would enter at the prompt: kdesu -c kfm -sw
-d Show debug information.
This option allow efficient use of KDE su in .desktop files. It
tells KDE su to examine the file specified by file. If this file
is writable by the current user, KDE su will execute the command
as the current user. If it is not writable, the command is
executed as user user (defaults to root).
file is evaluated like this: if file starts with a /, it is
taken as an absolute filename. Otherwise, it is taken as the
name of a global KDE configuration file. For example: to
configure the K display manager, kdm, you could issue kdesu -c
kdmconfig -f kdmrc
-i icon name
Specify icon to use in the password dialog. You may specify just
the name, without any extension.
-n Do not keep the password. This disables the keep password
checkbox in the password dialog.
Set priority value. The priority is an arbitrary number between
0 and 100, where 100 means highest priority, and 0 means lowest.
The default is 50.
-r Use realtime scheduling.
-s Stop the kdesu daemon. This is the daemon that caches successful
passwords in the background. This feature may also be disabled
with -n when KDE su is initially run.
-t Enable terminal output. This disables password keeping. This is
largely for debugging purposes; if you want to run a console
mode app, use the standard su instead.
While the most common use for KDE su is to run a command as the
superuser, you can supply any user name and the appropriate
More detailed user documentation is available from help:/kdesu (either
enter this URL into Konqueror, or run khelpcenter help:/kdesu).
Run kfmclient as user jim, and show the Konqueror icon in the password
kdesu -u jim -i konqueror kfmclient
