Restart PC safely if your distro crashes

It's weird, but in GNU / Linux we also have our impending PC crashes and there is a very simple method to safely restart it so forget about the button Reset.

We press the keys:

Alt + PrintPantall

And we become an octopus, consecutively typing the following key combination:


the combination also works:


But what exactly does this do?

R Returns control to the keyboard.
S Synchronize.
E Send the term signal to the processes.
I Send the kill signal to the processes.
U Unmount the file systems.
B Restart the system.

    And if you don't want to restart it, but turn it off with REISUO

      Exact. I missed putting it on, thanks for remembering it.

        In most of the posts that I see that talk about REISUB they also forget to comment on REISUO, so don't worry (?)

    Thanks @elav for the tip it was very useful to me, when I was presented with a blockage I used the «Reset» button. You are very right to apply it, you have to become an octopus or have an assistant.

      LOL. The good thing about that is that the hardware doesn't suffer .. I'm thinking of finding myself an "assistant" for that. And since my PC almost never hangs, because in the meantime I put it to do other tasks hahaha

    The big finger of the right hand on the ALT and with the other fingers of the same hand write REISUB while with the left hand you press PrintScreen.

      Hahaha I don't do it like that. I have big hands, so left thumb on Alt (left). Little finger of the right hand in PrintScreen. With my left hand I take care of the letters RESU and with the left IB hahahaha .. Quite an octopus. That reminds me of those who use VIM 😛

    The way to do it right is to press Alt + PrintPantall at the same time, but then release the PrintPantall key and only hold ALT…. and so with the other hand that is free to press the rest of the keys one by one (REISUB) until the equipment restarts ... 😉

    Hahaha, I remember I used this a while ago, but I never knew what each of the combinations did, thanks!
