Speed Test from the Command Line

For a lot of projects, I don't want the GUI, so I have to do everything from the command line (CLI). One thing I do on Windows a fair amount is speed tests, to ensure networking speeds are okay, and now I can do this from the Raspbian CLI.
Open a terminal and enter:

sudo apt-get install python-pip
sudo easy_install speedtest-cli

To start a test:

speedtest-cli

You should get an output like:

$ speedtest-cli

On a Pi Zero with a crappy eBay USB Nic I got:
Download: 3.52 Mbit/s
Upload: 2.91 Mbit/s

On a Pi Zero with a branded (Belkin) USB 2.0 Adapter I got:
Download: 44.40 Mbit/s
Upload: 17.00 Mbit/s

My max DL on my PC is 50Mb/s and my max UL is 18Mb/s, so the Pi Zero and Belkin are working very well.
