FYI, in bash, "sudo !!" re-runs the previous command with sudo.

That's not "funny" enough, unless the "!!" is replaced by an emoji.

    papln used multiple exclamation marks and is clearly insane. This incident will be reported.

I use it all the time! But also worth remembering that !$ is the object of your last command, so you could do something like

cp /some/tortured/path/to/file.txt /some/other/path/file.txt

chown myuser:myuser !$

Thanks for that little tip! It's a constant mistype for me...
