Examples of using the kill command

To kill a single process:

   ps
     PID TT STAT  TIME COMMAND
     9408 p9 S     0:00 ue temp2.xdh
     9450 pa S     0:01 -Tcsh (Tcsh)
     9501 pa T     0:00 less csh.1
     9503 pa R     0:00 ps
   kill 9501

This kills process number 9501. Notice that the ps command which is entered to check on the process ID's has the latest process number.

To kill a process that refuses to die:

   kill -9 9352

This makes a certain kill of process number 9352.

To kill a background job:

   jobs
   [1]  + Running              xterm -g 70x55
   kill %1
   [1]    Done                 xterm -g 70x55

This kills job number 1 (one); the only job that is currently running. The Bourne shell does not support this feature.

To kill more than one process:

   kill 8939 9543

This kills processes 8939 and 9543.
