NAME

       Gnome Xsu - ’su - username -c command’ for GNOME

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
       command,  a  username and a password.  If the username and password are
       correct xsu will execute the command as the entered  user.  So  if  the
       username 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
       application. This has been replaced with a special type of pipe to  the
       standard  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
       environment 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
       supported 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

       -t, --title WINDOWTITLE
              Set another window title

       -a, --set-display OSTNAME:PORT
              Sets the DISPLAY environment variable to :0 before starting  the
              command if no second argument is given else use HOSTNAME:PORT as
              XServer host.

       -m, --message MESSAGE

              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."
