Exactly. When you su root, $DISPLAY is not set, so you would have
to set it first, maybe like this:
#!/bin/sh
su root -c \
export DISPLAY=:0.0; \
xterm -geometry 80x25 -title 'App 1' -e 'app1'
xterm -geometry 80x25 -title 'App 2' -e 'app2' \

You could do this:
xterm -geometry 80x25 -title 'App 1' -e 'app1 ; csh'
which would start your prefered dialog shell when app1 has
finished. The dialog shell would run even if app fails (thatÄs
why I suggest using ; instead of ).
So basically the idea is open 4 terminals, execute a specific command
inside them but if the command finishes or stops, the terminal stays
{with a new prompt}.
This sould be able to be achieved using the example above.

hi to all the list,
i need some help... Is it possible to open four consoles as
root(authenticate yourself once), in each one run a specific program
and do this through a script? {bash or python).
i want to open 4 xterms in the four corners of the screen. In 3 xterms
i want to run specific applications needing root privileges and the
last i want it for administrative purposes.
what i have so far:
sudo xterm -e path/to/application1
sudo xterm -e path/to/application2
sudo xterm -e path/to/application3
sudo xterm
But this approach has the following problems:
1) i have only managed to get it to work as sudo not su
2) i haven't managed to position the 4 terminals correctly
in the 4 corners of the screen
Maybe this is a solution for you (or at least a point to start):
#!/bin/sh
xterm -geometry blahblah -title App 1 -e su root -c app1
xterm -geometry blahblah -title App 2 -e su root -c app2
xterm -geometry blahblah -title App 3 -e su root -c app3
xterm -geometry blahblah -title App 4 -e su root -c app4
The -geometry is set as ROWSxCOLS+X+Y, e. g. 80x25+0+0 for
the upper left corner. See man xterm for further options as
you could need them.
3) i want to be able to close and restart a single terminal.without
running again the whole script (this i am not sure if it is even
doable). For example if one of the applications hungs, then i want to
be able to restart this application, without running the whole script
again.
You could create a wrapper script that calls four scripts which
only start one of the four applications each.
~/bin/run_1:
#!/bin/sh
xterm -geometry blahblah -title App 1 -e su root -c app1
~/bin/run_2:
#!/bin/sh
xterm -geometry blahblah -title App 2 -e su root -c app2
~/bin/run_3:
#!/bin/sh
xterm -geometry blahblah -title App 3 -e su root -c app3
~/bin/run_4:
#!/bin/sh
xterm -geometry blahblah -title App 4 -e su root -c app4
~/bin/run_all:
#!/bin/sh
~/bin/run_1
~/bin/run_2
~/bin/run_3
~/bin/run_4
Not very elegant and tidy, but should work. You could add some
checking to the first script mentioned so it gets a clue which
application is *not* running and restart it when called, not
starting those that are running again (second session).
