Tags: command line Linux Requirements Access to the Linux or Windows command line interface. Procedure Linux: First, you will need to know the process ID. Running processes can be listed using the following command: ps -A Once you have obtained the process ID, you can request for the application or process to end by: kill #### where “####” is the process ID. If you want to force the process to end, you can use: kill -9 #### where “####” again is the process ID. You can use ps again to see if the process has terminated. Windows: Use: tasklist | findstr processName to find the process ID of the process you are trying to terminate. “processName” in the above command should be replaced by the name or part of the name of the process you are looking for. If you want a list of all processes, simply use: tasklist without redirecting the output to the findstr command. A sample command with sample output is: C:\Users\User>tasklist | findstr iexplore iexplore.exe 4632 Console 1 28,112 K iexplore.exe 4676 Console 1 92,356 K Then, once you have obtained the process ID, you can terminate it with: taskkill /pid #### where “####” is the process ID of the application or process you wish to end. More Information Linux: Type either: man ps man kill Windows: Type either: tasklist /? taskkill /? for more information.
