      NAME
           nice - run a command at lower priority

      SYNTAX
           nice [ -increment ] command [ arguments ]

      DESCRIPTION
           A high nice number results in low priority.  Low numbers
           result in high priority.  Nice executes command  with a
           lower scheduling priority by adding increment to its
           priority value.

           The normal priority of a user process is 20.  If increment
           is omitted, a value of 10 is assumed.  thereby setting the
           actual priority to 20+10, a lower priority than 20.

           Priorities 0 to 8 are reserved for system processes, 9 to 19
           are for device drivers, and 20 to 99 are for users.  An
           increment greater than 79 is taken to be equal to 79.

           Only the super-user may specify a negative increment, which
           would reduce the priority value to yield a higher priority.
           e.g., --10.

      SEE ALSO
           nohup(1), nice(2).

      DIAGNOSTICS
           Nice returns the exit status of the command.
