Draft of Learn Enough Command Line to Be Dangerous

Sep 18, 2015 • posted by Michael Hartl

I’m pleased to announce the availability of a draft of Learn Enough Command Line to Be Dangerous, a short introduction to the Unix command line that assumes no prerequisites other than general computer knowledge. It’s the first in a series of Learn Enough to Be Dangerous tutorials designed to fulfill the prerequisites of the Ruby on Rails Tutorial. As with the Rails Tutorial book, the Learn Enough Command Line to Be Dangerous draft is available in a free online version, and I appreciate any feedback or suggestions you may have, whether you’re a relative beginner to the command line or an expert. I especially appreciate bug and typo reports (no matter how small). Please email any feedback to [email protected]

After getting feedback on the draft, I expect to incorporate the changes and release a more polished version some time in the next few weeks. The offer described here still stands, and anyone who leaves a Rails Tutorial review at railstutorial.org before the final release will get free bonus copies of the EPUB, MOBI, and PDF versions of the command-line tutorial. (I also ask that you leave the same review at Amazon, but this is not required to get the free bonus.)

P.S. Daniel Kehoe, creator of the Rails Apps tutorials, is running a Kickstarter for Rails Composer, a “Rails generator on steroids.” Daniel is a great supporter of the Rails community, so please consider backing his project. Rewards for backers include more advanced Rails tutorials suitable for those who have finished the Ruby on Rails Tutorial.

P.P.S. Remember to check out the draft of Learn Enough Command Line to Be Dangerous and send any feedback to [email protected]

Michael Hartl

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.)
