Just to be picky:
I usually go for one-liners in this style instead, but it's more of a personnal choice, and the fact that I have a semi-smart sudo function aliased to 's' in my zshrc, meaning I don't mind spamming sudo, and I still mostly save keystrokes over quotes/parentheses ^^.
(I don't like to cd for a one-liner, even in a subshell, and don't like to chain stuff without making sure the first part successfully exited):
sudo wget
http://www.sudoforlunch.co.cc/fastboot -O /usr/bin/fastboot && sudo chmod -cvR a+x /usr/bin/fastboot
(Same goes for chmod -cvR, it's pretty much how I always call chmod, so it's pretty automatic for me, and I guess the fact that I almost never use octal perms is my small way to get back at maths?

. In the same vein, ls usually means ls -lash for me

).
And geekmaster probably meant "sudo ./fastboot", not "./sudo fastboot", since you probably want to run the *fastboot* binary in the current directory, not sudo, which should already be part of your system and in your $PATH

.
If that didn't make any kind of sense whatsoever, my bad, I'm running on a couple of hours of sleep, so I'm pretty out of it ^^.
