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 num���
       ber 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 signals from the
       controlling terminal.  The priority is incremented by 5.  Nohup  should
       be invoked from the shell with ‘&’ in order to prevent it from respond‐
       ing 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

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 com‐
       mands executed with ‘‘&’’ are automatically immune  to  hangup  signals
       while  in  the background.  There is a builtin command nohup which pro‐
       vides 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.
