I've never had any incidents with `sudo !!`, however, I should point out that zsh (maybe other shells as well) replaces the `!!` with the full command and requires another press of Enter.
$ rm -rf /root
rm: cannot remove `root': Permission denied
$ sudo !! # Does not run this, but returns the line below.
$ sudo rm -rf /root # Then you say, "Wait I dont want to do this."Interesting. Bash on my OS X box shows the command you're running, but doesn't give you a chance to cancel it. It looks like this:
$ rm -rf /root
rm: cannot remove `root': Permission denied
$ sudo !!
sudo rm -rf /root
# /root is now kaputI think it's meant for when you run a command normally, but then realize you should have sudoed (sudid?) it. Though in that situation, I would still be inclined to do "↑ esc a sudo ". It's not a lot more work, but it is a lot less uncertain.
Indeed. I find ctrl-p ctrl-a is faster than going to the cursors.
Whoops, thanks. Should have been ctrl-a, but spelling out muscle memory is, like, hard.
If you have lots of jitter and lag, i suggest using Mosh which I've found to be amazingly awesome when using it on Amtrak's spotty free wifi (3G uplink).
