ps -ugx

(The ps command on various systems may need options different from -ugx to get the desired results; check with the consultants if you have questions.) This shows a list of your processes, like the one below (some columns have been left out to save space):

USER       PID %CPU STAT  START    TIME   COMMAND
janedoe   6393  7.9  R    18:05    0:00   ps -ugx
janedoe   6256  0.0  IW   Sep  2   0:02   -csh (csh)
janedoe   4659  0.4  S    Jan 3  210:00   /usr/usc/spss-4.1/spss

If you see something under COMMAND that has SPSS in it, this means a process involving SPSS has been running for the amount of time under TIME. If you don't want any SPSS processes to be running, you should kill the process by issuing the following command:

kill -9 4659

which "kills" process number 4659. Please check your processes daily to guard against overuse of the machine by unintended processes. This is a courtesy to other users, besides being in your best interests.
