Linux SysRq commands are a lifesaver when your system freezes or becomes unresponsive. The kernel always responds to these commands, no matter what state the computer is in. However, if the kernel itself is completely locked up, that’s a different story. The SysRq feature is extremely useful when system issues occur. For example, if your Linux is frozen and stops responding to any input, you can use SysRq command to shut down or reboot the computer.
