nice -- execute a utility with an altered scheduling priority
nice [-n increment] utility [argument ...]
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 neg-
ative increment. The priority can be adjusted over a range of -20 (the
highest) to 20 (the lowest). A priority of 19 or 20 will prevent a
process from taking any cycles from others at nice 0 or better.
A positive or negative decimal integer used to modify the system
scheduling priority of utility.
The nice utility exits 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 will be that of utility.
The historic -increment option has been deprecated but is still supported
in this implementation.

The nice utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
A nice utility appeared in Version 6 AT&T UNIX.
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.
