Unix > run command in the background
nohup is a Unix command that is used to run another command while suppressing the action of the HUP (hangup) signal, enabling the command to keep running after the user who issues the command has logged out. It is most often used to run commands in the background as daemons. Output that would normally go to the terminal goes to a file called nohup.out if it has not already been redirected. This command is very helpful when we have to run a huge list of batch jobs which are inter-dependent. (from http://en.wikipedia.org/wiki/Nohup)
