NAME
     nice - execute a command at a low scheduling priority

SYNOPSIS
     nice [-number] command [arguments]

DESCRIPTION
     Nice runs command at a low priority.  (Think of low and slow).  If
     -number is specified, and if it is greater than or equal to 10 (the de-
     fault), nice will execute command at that priority.  The upper bound, or
     lowest priority that nice will run a command is 20.  The lower bounds or
     higher priorities (integers less than 10) can only be requested by the
     super-user.  Negative numbers are expressed as --number.

     The returned exit status is the exit value from the command executed by
     nice.

SEE ALSO
     csh(1),  renice(8)

HISTORY
     A nice command appeared in Version 6 AT&T UNIX.

BUGS
     Nice is particular to sh(1).  If you use csh(1),  then commands executed
     with ``&'' are automatically immune to hangup signals while in the back-
     ground.

     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.
