Speedtest from the CLI

Written by James McDonald

Awaiting a speed increase on you Internet connection but it’s not there yet?

Want to know within an hour when the speed increase happens?

Create a crontab entry

crontab -e

With this content

MAILTO=""
0 * * * * /Users/username/sites/speedtest/speedtest.sh >> /Users/username/sites/speedtest/output.log 2>&1

Install speedtest-cli

brew install speedtest-cli
# for parsing the json output
brew install jq

Create a script that calculates the Mbps value and set a LOWER value to send an email at in this case

#!/bin/sh
PATH=/usr/local/bin:/usr/local/sbin:~/bin:/usr/bin:/bin:/usr/sbin:/sbin

BITS=`speedtest-cli --no-upload --json | jq '.download'`
MBITS=1000000
CALC=`echo $BITS / $MBITS | bc`
# lowest Mbps value you will accept as the speed increasing
LOWER=4

if [ "$CALC" -gt "$LOWER" ]
then
	echo "The internet speed has risen to $CALC Mbps" | mail -s "Internet SpeedTest" james@toggen.com.au
	echo `date` "Yas"
else
	echo `date` "MBITS = $CALC"

fi

    How are you controlling which speedtest server the test is run against? In my experience, results vary, often significantly, based on the server that is used for the test.

      In short i’m not. Australia doesn’t have too many options on the east coast so it will be Sydney or Melbourne. And given the choke point is my internet connection I wasn’t overly worried
