Linux uses SPEEDTEST-CLI for speed measurement

Often we use Speedtest.net to test in Windows environments, but how to use speedtest for testing under Linux.
I use a centos6.7 environment that contains the Python environment so you can test it directly. If you don't have Python, install Python first.

Download script

Wget-o speedtest-cli https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py
chmod +x SPEEDTEST-CLI

Using tutorials

./speedtest-cli

Test and share

./SPEEDTEST-CLI--share
