Info is needed for better understunding linux.

[CrAzYoNi]

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.

Most of your questions can be answered by looking at the FHS. You may need to find a good Solaris reference for some of the directories that are unique to Solaris (th solaris docs site is a good place to start).

First off, good luck!

About your questions though, Solaris isn't a Linux distro, it is a *nix derivative like the BSD's and of course plain old Unix itself. The GNU system (Gnu's Not Unix) is a clone of that on which they put the Linux kernel. And the GNU/Linux system is what we generally refer to when we say Linux. Thus you can view Solaris as a distant relative

Is there a reason you ask specifically about Solaris? I mean, if you want to gain knowledge in Linux I think you can better get a Linux distro. On the other hand, if you want to get better acquainted with commercial (yet open) *nix, then of course Solaris is one of the well known players in the field.
