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

       nice [ -number ] command [ arguments ]

       nohup command [ arguments ]

       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 pri-
       ority, e.g. `--10'.

       Nohup executes command immune to hangup and terminate signals from the controlling  termi-
       nal.   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 person who logs in on the same terminal.

       nohup.out standard output and standard error file under nohup

       csh(1), setpriority(2), renice(8)

       Nice returns the exit status of the subject command.

       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.
