NICE(C)                              UNIX System V



     Name
          nice - runs a command at a different scheduling priority


     Syntax
          nice [ -increment ] command [ arguments ]


     Description
          The nice command is used to execute a command at a different
          scheduling  priority  than usual.  Each process has a ``nice
          value'' which is  used  to  calculate  its  priority.   Nice
          values range from 0 to 39, with higher nice values resulting
          in lower priorities. By default, commands have a nice  value
          of  20.  nice executes command with a nice value equal to 20
          plus increment.  If no increment is given, an  increment  of
          10 is assumed.

          The super-user may run commands with  priority  higher  than
          normal  by  using a double negative increment.  For example,
          an argument of --10 would decrement the default to produce a
          nice value of 10, which is a higher scheduling priority than
          the default of 20.

     Diagnostics
          nice returns the exit status of command.


     Notes
          If the default nice value plus increment is larger than  39,
          a  nice value of 39 will be used.  If a nice value less than
          zero is requested, zero will be used.

          Note also that this description  of  nice  applies  only  to
          programs  run  under  the Bourne Shell.  The C-Shell has its
          own nice command, which is documented in csh(C).
