Each process you start is usually completed within a few seconds. Sometimes a background process or a process without a controlling terminal hangs up and you will need to destroy this process by killing it.

To kill a process use the kill command.

   kill [-signal] process_identifier (PID)

Use the ps command if you need to find the PID of a process.
