Appendix B. Linux History and Background

Now that you have tried out a few Linux distributions and learned some things to do with it, are you wondering how Linux came about? How can a computer operating system and thousands of applications be free? Well, the truth is that the path to the Linux systems of today was not a straight line.

This appendix describes the history of UNIX, BSD, and free software development that has led to the Linux systems of today. After that, you can read some of the most common myths associated with Linux
