Nothing like posting what was already in this thread.
Note that doing things with sudo the way Ubuntu does it is dangerous
because if someone hacks into your computer (not likely if you have good
security set up) or someone happens to come by your computer while sudo
still keeps the password in memory, your giving full root access to said
interloper. That's why you only have to type the password once for
multiple sudo commands. (BTW, the timeout is adjustable)
A much safer way is to use su -c "foo" and only issue the one command,
but the quotes are needed, and that can become tiresome.
But remember, it is your system and how you choose to use it is your
decision. Just keep good security practices in mind and you're likely
to enjoy happy computing a lot longer.
