NAME

6       nice, nohup - run a command at low priority (sh only)
7

SYNOPSIS

9       nice [ -number ] command [ arguments ]
10
11       nohup command [ arguments ]
12

DESCRIPTION

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.

BUGS

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.
