foreword
When people usually use computers and mobile phones to surf the Internet, the speed of the network is often the indicator you are most concerned about, and we generally use professional network speed test software to judge the quality of the network according to the test data. Then this article will introduce the network speed measurement tool under the Linux command line, so that you can know your network speed at any time!

I believe everyone is familiar with this network test software. We usually use this software when testing network speed.
Introducing Speedtest CLI
Speedtest CLI brings the trusted technology and global server network behind Speedtest to the command line. Built for software developers, sysadmins, and computer hobbyists alike, Speedtest CLI is the first official Linux-native Speedtest application powered by Ookla®.
