Description Tobias Mueller 2011-01-19 14:48:44 UTC 
Description of problem:
I tried to set the affinity of a process following http://www.cyberciti.biz/tips/setting-processor-affinity-certain-task-or-process.html which reads "taskset 0x00000001 -p 13545". The usage of taskset currently reads: 
Usage: taskset [options] [mask | cpu-list] [pid|cmd [args...]]

which matches the command given above. I hence expected to be able to run
taskset 0x00000001 -p 11930
but it fails:
taskset: executing -p failed: No such file or directory
Comment 1 Karel Zak 2011-06-07 21:35:20 UTC 
Your command 

   taskset 0x00000001 -p 11930

does not match with expected and documented command options. You have to use

  taskset -p 0x00000001 11930
