nice(1) General Commands Manual nice(1) Name nice, nohup - execute a command at a lower priority Syntax nice [-number] command [arguments] nohup command [arguments] Description The command executes command with low scheduling priority (Bourne Shell only). If the number argument is present, the priority is incre- mented (higher numbers mean lower priorities) by that amount up to a limit of 20. The default number is 10. The super-user may run commands with priority higher than normal by using a negative priority, for example, `--10'. The command executes command immune to hangup and terminate signals from the controlling terminal. The priority is incremented by 5. The command should be invoked from the shell with an ampersand (&) 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. The syntax of is also different. Options -number Increments the priority by a specified number up to a limit of 20. The default is 10. Restrictions The and commands are particular to If you use then commands executed with an ampersand (&) are automatically immune to hangup signals while in the background. There is a built-in command which provides immunity from terminate, but it does not redirect output to nohup.out. The command is built into with a slightly different syntax than described here. The form ``nice +10'' nices to positive nice, and ``nice -10'' can be used by the superuser to give a process more of the processor. Diagnostics The command returns the exit status of the subject command. Files nohup.out standard output and standard error file under nohup See Also csh(1), getpriority(2), renice(8) nice(1)
