Good book for clearing all basics required for computing as it talks about unix system in general. Therefore, it's able to cover all the system that exists. (Except windows via it's syntax but internally it is somewhat same by philosophy) It's the basic book for command line you need for introductory and it's Appendix sections are really useful while referring later and using it for reference for work. I didn't read it's similar book for mac Authored by Mark G. Sobell, for it applies to linux distros and all other unix based systems. Some of the programs or commands may not work as intended as the system(Operating System I mean) you are using might be a little different than one used by author, but almost all of them work and if you search around the internet you will find it's alternative online easily.
This is the first book which introduce me to Linux. It let me to have keen interest in Linux. Although , it doesn't contain all information . But,is very good for beginners.
