-	  usage: taskset [-ap] [mask] [PID | cmd [args...]]
-
-	  Launch a new task which may only run on certain processors, or change
-	  the processor affinity of an exisitng PID.
-
-	  Mask is a hex string where each bit represents a processor the process
-	  is allowed to run on. PID without a mask displays existing affinity.
-
-	  -p	Set/get the affinity of given PID instead of a new command.
-	  -a	Set/get the affinity of all threads of the PID.
