If you want to check the current internet speed of your Linux server from the command-line, you can use a utility called fast, a minimal zero-dependency script, written in Go language for testing your internet download speed from the terminal, which is powered by Fast.com, Netflix and runs on Linux, Windows and Mac.
This speed testing tool is very simple and has no options whatsoever. Simply, download binary file for your architecture (fast_linux_amd64 for 64bit systems) in your home directory, set execute permission and run it directly from the terminal to test your server Internet speed.
$ wget https://github.com/ddo/fast/releases/download/v0.0.4/fast_linux_amd64 -O fast $ chmod +x fast $ ./fast
If you want, you can install it under /usr/local/bin directory on any Linux distribution by using the following commands.
$ wget https://github.com/ddo/fast/releases/download/v0.0.4/fast_linux_amd64 $ sudo install fast_linux_amd64 /usr/local/bin/fast $ fast
You can also install Fast on any Linux distribution using snap (requires snapd to be installed on the system).
$ snap install fast
