Nohup

:

nohup is a Unix command that is used to run another command while suppressing the action of the SIGHUP (hangup) signal, enabling the command to keep running after a user who issues the command has logged out. It is usually used to run commands in background as daemon (computer software)s. Output that would normally go to the terminal goes to a file called nohup.out if it has not already been redirected.

=Example=

$ # Start fetchmail daemon and log out. The daemon will continue in the background. $ nohup fetchmail -d 30 & $ exit
