nice(1)nice(1)Name
nice, nohup - execute a command at a lower priority
Syntaxnice [-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 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, 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.
