Hi all,
I know linux for couple of years as a lamer.
I dedcided to know it much better, so better that I'm trying my luck as system administrator

(wish me luck!!)
So I started to read some pdf's of Solaris (It's quite a good distrubtion, don't you think?!)
I need your help! I need you to explain me shortlly (or deeper if you have time) about the path's I wrote below:
- /dev/cua (What's for UUCP (Unix to Unix copy protocol) and for phisical\hardware device? is it related to networking device (is it the thing about it?)
- /dev/dsk & /dev/rdsk (What is it the raw device exaclly? what is the newfs command is?, I understund that the /dev/dsk is just symobol of the raw device...)
- /dev/fbs
- /dev/fd
- /dev/md
- /dev/pts
- /dev/rmt
- /dev/term (Is there should be all of the console\RS-232 devices?)
- /etc/lib
- /etc/opt and /usr/opt (What are the diffarences between those two?, Is it related to the ditrubtion update manager, e.g apt-get on debian systems?)
- /etc/rc#.d
- /etc/skel
- /usr/ccs
- /usr/demo
- /usr/dt
P.S Most of my time with linux I used Mandrive & Ubuntu (As I said I'm a lamer that wanna became a master

).
Thanks for you help\information in advantage!
Yours,
Yoni D.
