Worst of all, some programs that freeze or lock up do so in a way that even your operating system can't detect and inform you about, leaving you wondering if you have a problem with your mouse buttons or touchscreen. Regardless of what program won't close, or what the specific situation is, there are several ways to "force quit" a program in Windows:.

Though they might seem related, many of the methods for forcing a software program to close aren't the same as unlocking a locked file. See our article What Is a Locked File?

Here's how to do it:. Bring the program you want to quit to the foreground by tapping or clicking on it. Press and hold one of the ALT keys. While still holding the ALT key down, press F4 once. It's super important that you do Step 1. If a different program or app is selected, that's the program or app that's in focus and will close.

If you hold it down, then as each program closes, the next one that comes to focus will close down, too. This will keep happening until all your programs are shut down and, ultimately, you'll be prompted to shut down Windows.

So, only tap the ALT key once to exit the one app or program that won't close. That said, knowing this force-quit method can be particularly helpful if the batteries in your wireless mouse have quit, your touchscreen or touchpad drivers are making your life really difficult right now, or some other mouse-like navigation isn't working as it should.

If that doesn't work or you don't have access to your keyboard, right-click or tap-and-hold on the Desktop taskbar and choose Task Manager or Start Task Manager depending on your version of Windows from the pop-up menu that appears. Next, you want to find the program or app that you want to close and get Task Manager to direct you to the actual process that supports it. This sounds a bit hard, but it's not.

How To Quit Frozen Programs In Linux

I have put the code in a while loop because I want it to log continuosly. But if I run the bash script in the terminal, the cursor just keeps blinking suggesting that the file is indeed caught in an infinte loop.

Now i want to be able to quit this loop gracefully. I don't know how. I just close the terminal and force quit the process. How do i break out of the while loop as and when the user feels like quitting the program? If you get a blinking cursor you are probably not actually in a loop.

You are probably expecting input. If that doesn't work then open a new terminal and ps aux grep command where command is the name of the script you wrote and then kill the pid that is returned. Just an idea. What if you read value from a file, and instead an infinite loop, you test the value?
