Create a Command Line Speed Tester

I love little command line tricks like this...  This comes from an OSX Daily article here.

Create an alias to give yourself a quick way to launch an internet speed testing tool using wget.

Add the following line to your .bash_profile and now you just need to type 'speedtest' to launch the test.
alias speedtest='wget -O /dev/null http://speedtest.wdc01.softlayer.com/downloads/test10.zip'
If you don't have wget on your mac yet, then simply install homebrew by running...
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
After Homebrew is installed you can install wget using this command...
brew install wget
