Anybody who wants to test their connection speed can easily do so from a speed test web site — but that isn’t very geeky. Here’s how to do a test from the terminal prompt instead.
$sudo apt-get install curl
Testing Internet Connection Speed with Curl
This is pretty simple. Just copy and paste the following command:
$curl -o /dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip
The first thing to point out is that we’re using a test file from Softlayer, but if your connection is really fast, you might want to use a larger file from Thinkbroadband to properly test. Secondly, that -o switch is the lower case form of the letter O. It’s not a zero, and if you omit it, your terminal will turn into crazyville since curl will try to output to the screen — it’s also important because we’re outputting the file to /dev/null, which means it’ll basically be automatically deleted.
Testing Internet Connection Speed with Wget
If you prefer using wget, or that is what you have installed, the switch is the same. That is a capital letter “o” and it sends the output straight to null, so you don’t have any files to delete.
$wget -O /dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip
This file is only 100 MB, so if you have a really fast connection, this isn’t going to work very well, and you’ll want to find a bigger file to download from the site linked above.
