NICE(1) 						    BSD General Commands Manual 						   NICE(1)

NAME

     nice -- execute a utility with an altered scheduling priority

SYNOPSIS

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

DESCRIPTION

     nice runs utility at an altered scheduling priority.  If an increment is given, it is used; otherwise an increment of 10 is assumed.  The
     super-user can run utilities with priorities higher than normal by using a negative increment.  The priority can be adjusted over a range of
     -20 (the highest) to 20 (the lowest).

     Available options:

     -n increment
	     A positive or negative decimal integer used to modify the system scheduling priority of utility.

DIAGNOSTICS

     The nice utility shall exit with one of the following values:

     1-125   An error occurred in the nice utility.

     126     The utility was found but could not be invoked.

     127     The utility could not be found.

     Otherwise, the exit status of nice shall be that of utility.

COMPATIBILITY

     The historic -increment option has been deprecated but is still supported in this implementation.

SEE ALSO

     csh(1), getpriority(2), setpriority(2), renice(8)

STANDARDS

     The nice utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

HISTORY

     A nice utility appeared in Version 6 AT&T UNIX.

BUGS

     nice is built into csh(1) with a slightly different syntax than described here.  The form 'nice +10' nices to positive nice, and 'nice -10'
     can be used by the super-user to give a process more of the processor.
