NICE(1)             UNIX Programmer's 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 sig-
     nals from the controlling terminal.  The priority is incre-
     mented 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 person 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 buil-
     tin 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 posi-
     tive nice, and ``nice -10'' can be used by the super-user to
     give a process more of the processor.
