Carrying out a speed test is usually a convenient way of checking or monitoring the speed of your internet connection. In most cases, you would visit a popular site such as Ookla Speed Test which provides an elegant UI that gives you a clear picture of your bandwidth including download and upload speeds and the name of your ISP.
Developed by Ookla, Speedtest CLI is a command-line tool that is tailored for system administrators and developers, and command-line enthusiasts. It provides the capability of checking the internet speeds straight from your Linux terminal.
Speedtest CLI allows you to do the following:
- Check the bandwidth performance including metrics such as download, upload, and packet loss.
- Check the connection from your PC or even a remote server and IoT devices such as Raspberry Pi.
- Configure scripts to collect speed test results over a period of time.
- Save results in CSV or JSON.
Speedtest-cli works with Python 2.4-3.7 For best results, ensure that you have Python 3.6 and later since older versions have been deprecated.

Testing the internet connection speed using Speedtest-cli
Now, let’s begin testing the speed of our internet connection. You can run the speedtest-cli command in its basic form without any arguments as shown.
As you can see, the script begins by retrieving the testing configuration from speedtest.net and identifies your ISP. It then retrieves a list of possible servers, selects the best server, and proceeds to perform both the download and upload speed tests, and prints out the results on the terminal.
You can share the bandwidth results with others using the –share option.
$ speedtest-cli --share
A URL containing the results of the speed test is provided at the very end. This contains a PNG image of the speed test results.
Copy and paste the URL on a browser and hit ENTER to view the speed test statistics.
If you just want simplified output that only displays the download and upload speeds, use the –simple option.
$ speedtest-cli --simple
To print a list of possible servers based on physical distance, use the –list option.
$ speedtest-cli --list
If the output contains servers from different regions, use the grep command to filter the output based on your preferred server. Here, we are listing servers located in Nairobi.
$ speedtest-cli --list | grep -i Nairobi
For more command options, use the –help option.
$ speedtest-cli --help
