Mac OS X UNIX-oriented Tutorial Is there any Mac OS X tutorial/book that covers the UNIX part of this operating system? Topics like:


Managing daemons from the command-line
Package management
Install/Remove dmg's from the command-line
Environment variables
Users/Groups/Permissions management
CLI utilities
OS Directory structure
Location of dev headers, libraries, etc
Devices names


Most of the tutorials I found out there cover GUI applications and that kind of stuff. Is there any material that covers Mac OS X under the hood?
I suggest you to try:
Unix for OS X which is a good way to begin with Unix and with the Unix command line interface of Mountain Lion.
O'Reilly is a very good editor in the field of the Unixes environments.
