NAME
     nice -- execute a utility at an altered scheduling priority

SYNOPSIS
     nice [-n increment] utility [argument ...]

DESCRIPTION
     The nice utility runs utility at an altered scheduling priority, by
     incrementing its ``nice'' value by the specified increment, or a default
     value of 10.  The lower the nice value of a process, the higher its
     scheduling priority.

     The superuser may specify a negative increment in order to run a utility
     with a higher scheduling priority.

     Some shells may provide a builtin nice command which is similar or iden-
     tical to this utility.  Consult the builtin(1) manual page.

EXAMPLES
     $ nice -n 5 date

     Execute utility `date' at priority 5 assuming the priority of the shell
     is 0.

     # nice -n 16 nice -n -35 date

     Execute utility `date' at priority -19 assuming the priority of the shell
     is 0 and you are the super-user.

DIAGNOSTICS
     If utility is invoked, the exit status of nice is the exit status of
     utility.

     An exit status of 126 indicates utility was found, but could not be exe-
     cuted.  An exit status of 127 indicates utility could not be found.

COMPATIBILITY
     The traditional -increment option has been deprecated but is still sup-
     ported.

STANDARDS
     The nice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY
     A nice utility appeared in Version 4 AT&T UNIX.
