Synopsis
nice [+
n] command
Change the execution priority for command,
or, if none is given, change priority for the current shell. (See
also nice in Chapter 25.) The
priority range is -20 to 20, with a default of 4. The range seems
backward: -20 gives the highest priority (fastest execution); 20
gives the lowest. Only a privileged user may specify a negative
number.
-
+n Add n to the priority value (lower job priority).
-
-n Subtract n from the priority value (raise job priority). Privileged users only.
