NAME
nice, nohup − run a command at low priority
SYNTAX
nice [ −number ] command [ arguments ]
nohup command [ arguments ]
DESCRIPTION
The nice command executes command with low scheduling priority. If the number argument is present, the priority is incremented (higher numbers mean lower priorities) by that amount up to a limit of 20. The default number is 10.
The superuser may run commands with priority higher than normal by using a negative priority, such as “−−10”.
The nohup command executes command immune to hangup and terminate signals from the controlling terminal. The priority is incremented by 5. The nohup command should be invoked from the shell with “&” in order to prevent it from responding to interrupts by or stealing the input from the next person who logs in on the same terminal.
DIAGNOSTICS
The nice command returns the exit status of the subject command.
