nice - execute a utility with an altered scheduling priority
nice [-n increment] utility [argument ...]
nice runs utility at an altered scheduling priority. If an
given, it is used; otherwise an increment of 10 is assumed.
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).
The options are as follows:
A positive or negative decimal integer used to modify the system
scheduling priority of utility.
The nice utility shall exit with one of the following values:
1-125 An error occurred.
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.
csh(1), getpriority(2), setpriority(2), renice(8)
The historic -increment option has been deprecated but is
in this implementation.
The nice utility conforms to IEEE Std 1003.2-1992
A nice utility appeared in Version 6 AT&T UNIX.
nice is built into csh(1) with a slightly different syntax
here. The form `nice +10' nices to positive nice, and `nice
-10' can be
used by the superuser to give a process more of the processor.
