shell scripting, run in parallel processes

Question

#!/bin/ksh
##########################################################################
$JAVA_HOME/bin/java -jar SocketListener.jar 8182

run_something_else

exit 0

SocketListener is started, and shell is waiting while SocketListener don't die.

How can I run run_something_else and SocketListener at the same time

Run it in the background by suffixing the command line with an &. — Noufal Ibrahim

$JAVA_HOME/bin/java -jar SocketListener.jar 8182 &

add an ampersand(&) at the end.this will give control of the terminal to the next line and makes your SocketListener run in the background.

nohup can be used to run the process in the background as daemon.

nohup runsomethingelse &

You could background something else:

nohup run_something_else &

Nohup will guarantee that sumething_else will run even if your terminal closes. So it will make it ignore sighup
