Install Speedtest-cli on a Linux

The speedtest-cli written in Python. So make sure Python installed and working correctly:
python --version
python3 --version
lsb_release -a

Step 3: Check the Internet speed

Simply type the following command:
$ ./speedtest-cli
$ python speedtest-cli
Sample outputs:

To see speed values in bytes instead of bits pass the --bytes option:
$ ./speedtest-cli --bytes
To generate and provide a URL to the share results image pass the --share option:
$ ./speedtest-cli --share
Of course, you can combine both the options:
$ ./speedtest-cli --share --bytes

How do I specify a server ID to test against?

First, grab a server list, enter:
$ wget
To view a server ID, enter:
$ more speedtest-servers.php
To search a server ID, enter:
$ grep 'city-name' speedtest-servers.php
$ grep 'country-name' speedtest-servers.php
$ grep 'Tampa, FL' speedtest-servers.php

<server url="" lat="27.9709" lon="-82.4646" name="Tampa, FL" country="United States" cc="US" sponsor="Hivelocity Hosting" id="2137"  host="" />
<server url="" lat="27.9709" lon="-82.4646" name="Tampa, FL" country="United States" cc="US" sponsor="Rapid Systems" id="1296"  host="" />

OR just display a server ID:
$ grep 'Tampa, FL' speedtest-servers.php | egrep -o 'id="[0-9]{4}"'
Sample outputs:


Next use the server ID 2137:
$ ./speedtest-cli --server 2137
Sample outputs:
