<title>Description</title>
<para>&tdesu; is a graphical front end for the
&UNIX; <command>su</command> command for the Trinity Desktop Environment.
It allows you to run a program as different user by supplying the
password for that user. &tdesu; is an unprivileged program; it uses
the system's <command>su</command>.</para>

<para>&tdesu; 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.</para>

<para>This program is meant to be started from the command line or
from <filename>.desktop</filename> files.</para>

<title>Options</title>

<variablelist>
<varlistentry>
<term><option>-c <replaceable>program</replaceable></option></term>
<listitem><para>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: <userinput><command>tdesu <option>-c <replaceable>kfm
-sw</replaceable></option></command></userinput></para></listitem>
</varlistentry>
<varlistentry>
<term><option>-d</option></term>
<listitem><para>Show debug information.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-f <replaceable>file</replaceable></option></term>
<listitem><para>This option allow efficient use of &tdesu; in
<filename>.desktop</filename> files. It tells &tdesu; to examine the
file specified by <parameter>file</parameter>. If this file is
writable by the current user, &tdesu; will execute the command as the
current user. If it is not writable, the command is executed as user
<parameter>user</parameter> (defaults to root).</para>
<para><parameter>file</parameter> is evaluated like this: if
<parameter>file</parameter> starts with a <literal>/</literal>, it is
taken as an absolute filename. Otherwise, it is taken as the name of a
global &tde; configuration file. For example: to configure the K display
manager, <application>tdm</application>, you could issue
<command>tdesu <option>-c tdmconfig -f
tdmrc</option></command></para></listitem>
</varlistentry>
<varlistentry>
<term><option>-i</option> <replaceable>icon name</replaceable></term>
<listitem><para>Specify icon to use in the password dialog.  You may specify
just the name, without any extension.</para>
</listitem>
</varlistentry>

<varlistentry>
<term><option>-n</option></term>
<listitem><para>Do not keep the password. This disables the <guilabel>keep
password</guilabel> checkbox in the password dialog.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-p</option> <replaceable>priority</replaceable></term>
<listitem>
<para>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.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-r</option></term>
<listitem><para>Use realtime scheduling.</para>
</listitem>
</varlistentry>

<varlistentry>
<term><option>-s</option></term>
<listitem><para>Stop the tdesu daemon. This is the daemon that caches
successful passwords in the background.  This feature may also be disabled with
<option>-n</option> when &tdesu; is initially run.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>-t</option></term>
<listitem><para>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 <command>su</command> instead.</para> </listitem>
</varlistentry>
<varlistentry>
<term><option>-u</option> <replaceable> user</replaceable></term>
<listitem><para>While the most common use for &tdesu; is to run a command as
the superuser, you can supply any user name and the appropriate
password.</para>
