How Do I Lock a Linux Machine?
Contents

You can freeze a terminal window on a Linux system by typing Ctrl+S (hold control key and press “s”). Think of the “s” as meaning “start the freeze”. If you continue typing commands after doing this, you won’t see the commands you type or the output you would expect to see.

What is Ctrl S in Linux?

Ctrl+S – pause all command output to the screen. If you have executed a command that produces verbose, long output, use this to pause the output scrolling down the screen. Ctrl+Q – resume output to the screen after pausing it with Ctrl+S.

What does Ctrl S do in terminal?

Ctrl+S: Stop all output to the screen. This is particularly useful when running commands with a lot of long, verbose output, but you don’t want to stop the command itself with Ctrl+C. Ctrl+Q: Resume output to the screen after stopping it with Ctrl+S.
