NICE(1) General Commands Manual NICE(1)
NAME
nice, nohup - run a command at low priority (sh only)
SYNOPSIS
nice [ -number ] command [ arguments ]
nohup command [ arguments ]
DESCRIPTION
Nice 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 super-user may run commands with priority higher than normal by using a negative priority, e.g. `--10'.
Nohup executes command immune to hangup and terminate signals from the controlling terminal. The priority is incremented by 5. Nohup
should be invoked from the shell with `&' in order to prevent it from responding to interrupts by or stealing the input from the next per-
son who logs in on the same terminal.
FILES
nohup.out standard output and standard error file under nohup
SEE ALSO
csh(1), setpriority(2), renice(8)
DIAGNOSTICS
Nice returns the exit status of the subject command.
BUGS
Nice and nohup are particular to sh(1). If you use csh(1), then commands executed with ``&'' are automatically immune to hangup signals
while in the background. There is a builtin command nohup which provides immunity from terminate, but it does not redirect output to
nohup.out.
Nice is built into csh(1) with a slightly different syntax than described here. The form ``nice +10'' nices to positive nice, and ``nice
-10'' can be used by the super-user to give a process more of the processor.
