NAME

       nice - run a program with modified scheduling priority

SYNOPSIS

       nice  [-n  adjustment] [-adjustment] [--adjustment=adjust-
       ment] [--help] [--version] [command [arg...]]

DESCRIPTION

       This manual page documents the GNU version of nice.   Note
       that  most shells have a built-in command by the same name
       and with similar functionality.

       If  no  arguments  are  given,  nice  prints  the  current
       scheduling  priority, which it inherited.  Otherwise, nice
       runs  the  given  command  with  its  scheduling  priority
       adjusted.   If no adjustment is given, the priority of the
       command is incremented by 10.  The superuser can specify a
       negative adjustment.  The priority can be adjusted by nice
       over the range of -20 (the highest priority)  to  19  (the
       lowest).

   OPTIONS
       -n adjustment, -adjustment, --adjustment=adjustment
              Add  adjustment instead of 10 to the command's pri-
              ority.

       --help Print a usage message on standard output  and  exit
              successfully.

       --version
              Print  version  information on standard output then
              exit successfully.
