6 nice, nohup - run a command at low priority (sh only)
7
9 nice [ -number ] command [ arguments ]
10
11 nohup command [ arguments ]

14 Nice executes command with low scheduling priority. If the number
15 argument is present, the priority is incremented (higher numbers mean
16 lower priorities) by that amount up to a limit of 20. The default num‐
17 ber is 10.
18
19 The super-user may run commands with priority higher than normal by
20 using a negative priority, e.g. `--10'.
21
22 Nohup executes command immune to hangup and terminate signals from the
23 controlling terminal. The priority is incremented by 5. Nohup should
24 be invoked from the shell with `&' in order to prevent it from respond‐
25 ing to interrupts by or stealing the input from the next person who
26 logs in on the same terminal.

29 nohup.out standard output and standard error file under nohup

35 Nice returns the exit status of the subject command.
36
38 Nice and nohup are particular to sh(1). If you use csh(1), then com‐
39 mands executed with ``&'' are automatically immune to hangup signals
40 while in the background. There is a builtin command nohup which pro‐
41 vides immunity from terminate, but it does not redirect output to
42 nohup.out.
43
44 Nice is built into csh(1) with a slightly different syntax than
45 described here. The form ``nice +10'' nices to positive nice, and
46 ``nice -10'' can be used by the super-user to give a process more of
47 the processor.
