The screen is interactive and the only way to view the output.

The exec script covers keeping the Java server running only if it doesn't consume all available memory and the OS doesn't kill all of the processes.

The exec script is executed in the screen to run, view, and interact with the server with ./exec .

When the machine the server is on is rebooted, I would like a script to cd to the server dir, start a screen with screen -S server1, then execute the exec script within the screen with ./exec . Then have the script check to make sure all of the processes are running. If not, restart them.

Sorry for not being able to explain everything very precise or easily.

dmxgetscreencount

DMXGetScreenCount(3)					     Library Functions Manual					      DMXGetScreenCount(3)

NAME

       DMXGetScreenCount - determine number of back-end screens

SYNOPSIS

       #include <X11/extensions/dmxext.h>

       Bool DMXGetScreenCount(Display *dpy,
			      int *screen_count);

DESCRIPTION

       DMXGetScreenCount()  returns  the  number  of back-end screens that a Xdmx(1) server controls.  Since a DMX screen usually fills all of the
       available area on a back-end server, there is usually a one-to-one correspondence between DMX screens and backend servers.  However, it	is
       also  possible  for a DMX screen to cover only part of the available area on a back-end server, and for more than one DMX screens to occupy
       different parts of the visible area on the same back-end server.

       A DMX screen may be managed as a regular X screen in the Xdmx(1) server or may be joined with other DMX screens using Xinerama.

RETURN VALUE

       DMXGetScreenCount() sets screen_count and returns True unless there is a protocol error.

NOTES

       If Xinerama is active, only one logical screen will be available to clients of the Xdmx(1) server.   However,  this  call  will	accurately
       reflect the number of composite back-end screens that the Xdmx(1) server is using.
