Comprehensive books on Linux?
I am using Ubuntu several years, but want to really study about how Linux works, and was wondering what books you recommend. Thanks!!
The best real book I have found is UNIX and Linux System Administration Handbook Everyone will learn something from this book. It is awesome.
For Ubuntu specifically, the Official Ubuntu Documentation is fairly hard to beat.
If you really want to get a good understanding of linux, why not build your own installation from scratch?
