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
script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.

WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
privileged user, that is, root. Be sure that typescript is not a link before running script.
