Yes well, thanks for the tip – One of those things many of us probably “know” but never use.

I’m not sure whether or not the xkcd cartoon would have been improved if it had been used:

Make me a sandwhich.

What? Make it yourself.

Sudo !!

Okay.

Less funny I think.

Here’s a bash function that will either pass its arguments to sudo, or if there are no arguments, pass the previous command to sudo:

then
sudo $@
else
sudo $(fc -ln | tail -n1)
fi
}
