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 negative
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.
Available options:
-n
incrementThe nice
utility exits with one of the
following values:
nice
utility.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.
