Useful commands

Kill unresponsive process

An unresponsive processe/service ignores the kill command. In order to shut down the process immediately use

kill -9 PID

where PID is the process ID.

This is equivalent to

kill -SIGKILL PID

The kill -SIGKILL command bypasses the standard shutdown routine and unsaved data will be lost.
