I've written a short 5 chapter book, about the command line interface called "Working the Command Line". It's aimed at beginners and people with limited CLI experience to broaden their skills and become more comfortable in the CLI and now the video series is nearly ready.
It's on sale as an ebook from A Book Apart for $8 here:

The video series covers the same top level chapters, but also includes a lot more detail and tips as I walk through each section. I also intend to record a bonus chapter of video on more advanced (web related) CLI topics (more on this later though).
Entering your email in the form below will a) let me contact you when it's finished and live, b) gauge interest (though the video series is nearly finished so it should happen either way).
Note: your email will not be shared with anyone or used for anything other than letting you know the video is available to buy.
