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.@[email protected] I've been working in the bash shell since 1993 and did not know

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'!

redo
