PRO: Out of three cheat sheet apps this is the only one that could tell me what this means, "apt." Go figure. Very simplistic, but loaded with information. CON: When I type in a search it cuts off the lower portion of my text. Also, the text is incredibly thin, small and hard to see. I would love to see a black & White theme option. Pix9/Adro16

This is a good attempt, and the author's heart is clearly in the right place, but this is one of those things that really does need collaboration. The tips section needs work, and the program references are inconsistent in whether or not they have any text formatting. Many references link to tl;dr rather than having any content, which defeats the purpose of an offline reference. All in all, it's a good example of too large of a scope too soon.

This is an excellent resource for reference and learning on the Linux command line. The command line syntax remains accurate, but there are some typographical errors in other text. This may be the result of German to English translation. Despite this, the errors are not enough to prevent learning. I still recommend the application if you are new to the Linux command line.
