sudo !! to rerun last command as sudo.

history can be paired with !5 to run the fifth command listed in history.

Fifth as in fifth most recent command or fifth oldest?

I believe it's the fifth oldest - I think !-5 will get you the fifth impost recent, but I was shown that and haven't put it into practice.

The most common usecase I do is something like history | grep docker to find docker commands I've ran, then use ! followed by the number associated with the command I want to run in history.

@papertowels@lemmy.one I've been working in the bash shell since 1993 and did not know sudo !! was a thing. Good lord, I no longer have to press up, press crtl-left a bunch of times, then type sudo enter space anymore. And I can give it an easy-to-remember alias like 'resu' or 'redo'! Ahahaha, this changes everything! Thank you!!

Love these, I used a terminal select from history with fuzzy finding to do the !5 as redo
