Then you want a crontab to make sure 'exec' is running?
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.

NAME
startfluxbox - start a fluxbox session SYNOPSIS
startfluxbox DESCRIPTION
startfluxbox is a script which runs the file ~/.fluxbox/startup If it doesn't exist it will be generated. startfluxbox should be started from your ~/.xinitrc if you use startx, or ~/.xsession if you run a display manager, like xdm. FILES
~/.fluxbox/startup This file contains all commands that should be executed before fluxbox is started. The initial file contains helpful comments for beginners. It also starts fluxbox. EXAMPLES
The default ~/.fluxbox/startup is as follows: #!/bin/sh # # fluxbox startup-script: # # Lines starting with a '#' are ignored. # Change your keymap: xmodmap "$HOME/.Xmodmap" # Applications you want to run with fluxbox. # MAKE SURE THAT APPS THAT KEEP RUNNING HAVE AN ''&'' AT THE END. # # unclutter -idle 2 & # wmnd & # wmsmixer -w & # idesk & # And last but not least we start fluxbox. # Because it is the last app you have to run it with ''exec'' before it. exec fluxbox # or if you want to keep a log: # exec fluxbox -log "$fluxdir/log" If you need to start applications after fluxbox, you can change the exec fluxbox line above to something like this: exec fluxbox & fbpid=$! sleep 1 { xsetroot -cursor_name left_ptr -fg white -bg black & ipager & gkrellm2 & } & wait $fbpid So xsetroot, ipager, and gkrellm2 will all be started after fluxbox, after giving fluxbox 1 second to startup. For more details on what else you can do in this script, see sh(1), or the documentation for your shell. AUTHORS
