Kill a suspended process on Linux Terminal

Problem

A process stops responding normally. When you try to exit it using Ctrl C, it prints ^C instead. Whatever you type just prints on the screen, the process seems to be stuck, and you hate restarting a new instance of the terminal.

Solution

Try Ctrl \

If that doesn't help, send the process of the background using Ctrl Z. Then bring it back:

$ fg

If even that doesn't help, send it to the background again, and:

$ kill $!

There you have you terminal free again. No more closing of the terminal instance because of a frozen process. Happy hacking!
