Introduction
This page briefly describes how to start background processes ("daemons") on UNIX.
The & Sign
An & sign placed at the end of shell commands instructs the shell to run the program as a background process. The shell will display the process's id ("pid"). Use the "kill" command to stop the process passing in the pid of the background process.
nohup
Use the nohup command to run a background process on UNIX that never terminates even when you log off
Run "man nohup" from your UNIX shell for more information
Example:
nohup perl -e "for(;;){sleep(100);}" &
Starting Daemons at Boot Time
Specify the script name followed by the & sign
