    sudo !! Is nice but I mostly use the up arrow to repeat something long and complicated I did 10 minutes ago. The joke there is sometimes that takes too long too. So that’s where history | grep 'keyword' is nice

      history | grep 'keyword'

      If it’s bash, it’s using readline, which is in emacs-like mode by default, and so you can probably use Control-R to do a reverse i-search (incremental search). Enter to invoke the command. Control-C to abort i-search.

      If a search matches multiple candidates, tap Control-R multiple times to cycle back through results.

      EDIT: Also, ! has a built-in search, so if you are sure of the starting string, you can just do that. I generally prefer to use the interactive search to confirm that I’m not invoking something wonky.

      $ touch a
$ rm a
$ touch a
$ !rm
rm a

      sudo !!

      Never again, lol.

      Last time I did that, it was not what I remembered. I didn’t break anything, but it was close enough that I scared the shit out of myself.
