Yesterday on Twitter, Dave Hamilton tweeted…
`brew install speedtest` is one of the best things I ever did on my Macs. `speedtest` from Terminal rocks. No flash, no browser. W00t!

What is this speedtest exactly? And what is brew, you may also be wondering? You may also be wondering why, if you have brew, Dave's command doesn't work…that's because it's actually brew install speedtest_cli…but I'm getting ahead of myself.
speedtest is a command line interface (i.e. Unix app run from Terminal) to the connection speed tests at Speedtest.net—you get the results without the fancy animated graphics. And Brew is "the missing package manager for macOS." In other words, it's an app to help you install (and uninstall) other apps.
Here's how speedtest looks in its default mode—note that I've sped things up greatly for the GIF…
Much nicer to me, though, is the simplified version:
$ speedtest_cli --simple Ping: 9.482 ms Download: 94.23 Mbit/s Upload: 68.66 Mbit/s
No animated dots, just three lines with the results. As you might expect if you read here regularly, I also wrote a Keyboard Maestro macro (of course I did!) that makes it really easy to run the simple version of the test, and does some editing of the output to simplify the display:
If you'd like to install speedtest (and maybe add the macro)—even if you don't want to install Brew to do so—keep reading…
With Brew installed
If you have Brew installed, installation is as simple as brew install speedtest_cli in Terminal. Note that the installed name is simply speedtest, not speedtest_cli.
Without Brew installed
The project is hosted on Github, and there are many ways to install from there. Perhaps the easiest would be via Terminal:
$ curl -Lo speedtest https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py $ chmod +x speedtest $ mv speedtest path/to/where/you/want/it/to/live
Obviously, you need to edit the third line to move the app to the directory where you'd like it to live, unless your system has a very unique directory structure that matches the above!
As seen above, usage is as simple as typing speedtest or speedtest --simple in Terminal. There are other options, like --secure for a secure connection; type speedtest --help for a full list.
But running from Terminal means you have to be in Terminal, and this is something that I'd like to be able to run from wherever. Enter Keyboard Maestro…
I actually wrote this twice; once in super-simple form, and then a fancier version that does some processing to change the display of the output.
The super simple version
This is a four-step macro [download], in which three of the steps don't really do anything at all:
The first and last steps lock the macro so it can't be activated twice at the same time (important for a slow-running macro like this). The second line displays a notification, letting you know the macro is running and that the results will also appear in the notifications area of the screen. The third line just calls speedtest. Note that you'll need to provide the full path to the program; I used Brew to install, so mine is in /usr/local/bin.
In its simple form, the notification contains the three output lines from simple mode, scrunched to fit on two lines in Notification Center:
And while this is fine, I decided I wanted it to fit on one line, and I didn't need long words to describe things. And so that led to…
The fancy version
The macro itself [download] is basically the same as the simple version, except instead of calling speedtest directly, I call a script:
To use this macro, you'll need to recreate my script, and modify the macro to point to your version…unless your macOS username also happens to be robg, you store your scripts in a folder named bin in your home folder, and you named your script pysts.
The script is a Python script, the first I've ever written. And before I post the code, here's the disclaimer: I know there are myriad ways to process the speedtest output that are probably way more efficient than my solution. A script isn't required, in fact—some combination of sed and piping and whatnot will get the job done. But for me, with my level of skill, the Python script works well because it's easy to modify, and I'll understand what I did when I look at it in the future.
So here's the code...
# coding: utf-8
# Run the speedtest, capture the output
# Edit this path to match the location of your speedtest
SpeedNums = subprocess.check_output(["/usr/local/bin/speedtest", "--simple"])
# Do my string replacements
SpeedNums = string.replace(SpeedNums, '\n', ' ')
SpeedNums = string.replace(SpeedNums, 'Ping:', '⬌')
SpeedNums = string.replace(SpeedNums, 's Upload:', 's ⬆')
SpeedNums = string.replace(SpeedNums, 'ms Download:', 'ms ⬇')
Knowing nothing at all about Python, this (of course) took longer than expected. Things I didn't know were plentiful, including basic stuff like "Wait, you can't process strings unless you first import a string module?" But it works, and it seems pretty efficient—the waiting time is 99% speedtest testing time, not the script. The output is the one-line version seen near the top of this tip.
With this very simple script, I can run a connection speed test by either typing a simple phrase (=spd= for now), or by selecting my speed test entry in Keyboard Maestro's menu bar icon. (I didn't want to waste a hot key for something I won't run all that often.)
