    The whole book is quite basic and if you are a seasoned Ruby developer, you might not learn too many things However I must admit that it covers all the minimum knowledge that any person doing a command line application must have Good if you want to solidify your knowledge of CLI programming, great if you are a beginner or expose yourself randomly to Ruby when doing small programs.

    It was an easy read because I am familiar with testing CLI apps The book discusses essential gems It feels like reading a long version of a README file If you have time for that, read this Otherwise, you re better off reading documentation of gli, ronn and a few other gems.

    Great book if you are a beginner that is interested in building small, basic command line applications, but if you re a bit experienced with command line applications and looking for a book to expand your knowledge this isn t for you.

    If you re a looking for a introduction to how write CLI applications, it s really a good choice.It does not cover the tests parts very well, but explains the hard parts of tests like simulating changes in file system.

    3.5 5 Not a bad introduction to command line apps, and lots of good information sprinkled throughout, but it wasn t quite what I was expecting.
