Learn Enough Command Line on Amazon.com

Aug 16, 2016 • posted by Michael Hartl

I'm pleased to announce that Learn Enough Command Line to Be Dangerous is now available at Amazon.com.

The Unix command line is the single most important foundational skill for aspiring software developers, and Learn Enough Command Line to Be Dangerous has been called "the best beginners guide to bash [the most popular command-line program]".

The price of Learn Enough Command Line at Amazon will eventually be $9.99, but I'm offering a 30% launch discount for the first week, so it's only $6.99 if you buy now. In addition to the native Kindle format, every purchase includes a claim link for free copies of the PDF & EPUB formats as well.

Even if you don't want to buy a copy, it would be much-appreciated if you could leave a review of the tutorial at Amazon.

As always, Learn Enough Command Line to Be Dangerous is available for free online, and for direct purchase as well, but having the ebook up at Amazon means even more people can find the Learn Enough tutorials and start learning technical sophistication.

Get 30% off Learn Enough Command Line to Be Dangerous at Amazon.com through Tuesday 8/22.

If you could leave a review that would also be much-appreciated!

I’m Michael Hartl—author, educator, and entrepreneur. I’m probably best known as the creator of the Ruby on Rails Tutorial, a book and screencast series that together constitute one of the leading introductions to web development. Once called his “favorite book” by Wikipedia founder Jimmy Wales, the Ruby on Rails Tutorial currently has over 150 5-star reviews at Amazon. I’m also (in)famous for creating Tau Day and The Tau Manifesto, which have inspired an international movement dedicated to the proposition that “pi is wrong.” (For example, as a result of The Tau Manifesto, MIT releases their admissions decisions each year at “Tau Time” (6:28 p.m.), and typing tau/2 at Google yields 3.14159…) Finally, I’m a founder of Softcover, a publishing system and sales platform for technical authors, which among other things powers both The Tau Manifesto and the Ruby on Rails Tutorial.

I’m a graduate of Harvard College and have a Ph.D. in Physics from Caltech, where I studied black hole dynamics and was an award-winning instructor in theoretical and computational physics. I’m also an alumnus of Y Combinator, the entrepreneur program that has produced companies such as Dropbox and Airbnb. (Alas, my own Y Combinator startup was neither Dropbox nor Airbnb.)
