SYNOPSIS

       xsu [ OPTION... ]

DESCRIPTION

       Gnome  Xsu,  is an interface for the command `su - username -c command`
       in Gnome. When the user executes xsu, he will be prompted  for  a  com-
       mand, a username and a password.  If the username and password are cor-
       rect xsu will execute the command as the entered user. So if the  user-
       name was root, then the command will be executed as root.

SECURITY

       Gnome  Xsu  uses  the standard su binary to gain it's root access. This
       way, all security issues should be solved.

       The security of all older xsu versions was very bad. With  xsu  version
       0.1.0 I introduced the use of a pipe to a secured non-Gnome SUID appli-
       cation. This has been replaced with a special type of pipe to the stan-
       dard su application.  For example the one from GNU sh-utils can be used
       with Gnome Xsu.

ISSUES

       Gnome Xsu uses the Unix 'su' execute the command. This means that  your
       DISPLAY environment variable of the user must be set correctly. You can
       put for example export DISPLAY=:0 in the file /etc/profile (bash).  You
       can  also use the option --set-display which will set the DISPLAY envi-
       ronment variable to ":0" before starting the command.

OPTIONS

       This program follows the usual  GNU  command  line  syntax,  with  long
       options  starting with two dashes (`--'). A summary of the options sup-
       ported by xsu is included below.




       -c, --command COMMAND
              Set the command to be executed


       -u, --username USERNAME
              Set the username to execute the command as


       -i, --icon FILENAME
              Load another icon
              Set the message to be displayed; you can use the character ^  in
              your  message if you want to use a new line, and the character ~
              if you want to use a tabulation.  If no message is set, then the
              default message will be used


       -d, --unadaptable
              Disables the username and command textboxes if possible


       -e, --hide
              Hides the username and command textboxes if possible


       --     Stops  commandlineparsing  and  replaces  the  -c argument.  All
              other arguments that are behind the --  argument  are  collected
              and will be used as the new -c argument.

EXAMPLES

       xsu  -c  "gmenu"  -u  "root"  -m  "To start the Menu Editor^you have to
       enter^the root password^here."

BUGS
