sudo !!to rerun last command as sudo.historycan be paired with!5to 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
!-5will 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 dockerto 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!!We're all learning tricks in this thread! Grateful for all y'all nerds.
Love these, I used a terminal select from history with fuzzy finding to do the !5 as
redo
