Ubuntu has a command that lists all current processes.If you find the process ID,you can kill it by kill command.

Type following to list all your own running processes

ps ux

And use command to kill any process you want,the second column is PIDnumber.

kill -9 PIDnumber

Ubuntu also has a graphical program to view current processes.Navigate to System–>Administrator–>System Monitor,you will see system processes at Process tab,kill any by select it and click “End Process” button.

    I have multiple instances opened of the same application, but some of those instances get hung at anytime and I want to kill the, but without killing the ones which are still running… ps -ef is not clear regarding which are are ones hung… they are being lunch by the same command so there is no way from CLI to know the PID of the ones hung… I tried right click–>close in Gnome but the application didn’t die! Please help!!! How can I make sure which is the PID for a hung application when I have multiple instances of the same application running? Is there any way to move the hung application to a “Trash” Workspace and the tell Ubuntu to kill all the applications in “Trash” workspace? Any other idea is welcome. Thanks in advance!
