I find that sometimes my Linux will stop responding, so I need to switch to another terminal with CtrlAltF2, and type a command to kill the
top CPU usage process or
top IO usage process, so that the system can be responsive again.
This command should be short and execute quickly.
I know the command
kill, but I do not know how to get the
top-est process PID or name.
I will add this command into shell alias or function.
