NICE(1CSH)              COMMAND REFERENCE              NICE(1CSH)



NAME
     nice - run a command at a different priority (csh built-in)

SYNOPSIS
     nice [ {+-}number ] [ command [ args... ] ]

DESCRIPTION
     With no command arguments, nice raises or lowers the
     priority of the current shell.  With a command, that command
     is run in a separate shell with the priority raised or
     lowered.  Non-superusers may only lower the priority, and
     thus may only use the `+' before the number.  The superuser
     may raise the priority by using the `-' before the number.

     The default number argument is `+4'.

     The valid range of priorities is -20 to 20, with -20 being
     the highest, 20 the lowest, and 0 the normal default
     priority.

OPTIONS
     +number
         Make the new priority equal to the old priority plus the
         given number, with a maximum of 20.

     -number
         Make the new priority equal to the old priority minus
         the given number, with a minimum of -20.

EXAMPLES
     To run the command ``make myprog'' at a priority that is 4
     lower than the current priority, use either of the following
     command lines.



          nice +4 make myprog
          nice make myprog


RETURN VALUE
     The return value is the value returned by the command
     executed (0 if no command), or 1 if the command was not
     found.

CAVEATS
     The syntax for nice is very different from nice(1).

     Once the current shell is niced down, its priority can only
     be raised by the superuser, so it is recommended that
     nice(1) be used in an alias for nice so that accidents are
     avoided.
