In order to test our broadband speed, we generally visit online speed testing sites like Speedtest.net or Fast.com, however there are many a times we may want to test the speed of the internet from the command line (terminal).
Whether you are a power user who normally uses command line over the GUI, or simply want to monitor your website speed without visiting an online site filled with ads, then there are couple of ways you can check your internet speed from the terminal on your OS. These commands will work on all operating systems including Windows, Mac and Linux.
In order to test the net speed from command line, we will have to install a few programs. These programs require NodeJS which is available for all operating systems.
Head over to the NodeJS downloads page and grab the latest version suitable for your Operating System. You may already have NodeJS installed on your system. To check whether NodeJS is installed or not, run the command ‘node -v’ in terminal (or cmd).
$ node -v v8.2.1
Once you have NodeJS installed, you will be able to install publicly available npm modules. These modules are generally open source programs or libraries which serve different purposes. For example, we will make use of two node modules speed-test and fast-cli below to check internet speed. Both the programs are free, open source and developed by Sindre Sorhus.
Internet speed via speed-test CLI
Using the terminal, install speed-test module with the following command:
$ npm install --global speed-test
It will take a while for the module to get installed. Once it finishes installing, you will be able to run the command ‘speed-test’ from the command line. Running the command ‘speed-test’ will perform a speed test via your terminal and present a textual result as shown below:
$ speed-test Ping 34 ms Download 11.9 Mbps Upload 12 Mbps
The program tests your internet connection speed and ping using speedtest.net and displays the result in the terminal itself.
If you want a more detailed result, you can run the command ‘speed-test -v’ and it will give a verbose output which includes the server location and distance. You can refer to the documentation of this open source program on GitHub.
Internet speed via fast-cli
Alternatively, you can install and use fast-cli if you want to test your internet speed using fast.com.
Using the terminal, install fast-cli module with the following command:
$ npm install --global fast-cli
Once it finishes installing, you will be able to run the command ‘fast-cli’ from you terminal and will get internet speed result as show below:
$ fast / 12 Mbps
You can refer to the documentation of this open source program on GitHub.
Internet speed Comparison and Fixing Slow Internet
Command line utilities shown above are helpful in performing internet speed checks and for doing comparison of internet speed. If you are facing slow internet speed then you can use these command line tools to check your internet speed without the need of opening a browser and visiting any site.
