By unic I suspect that you are referring to linux? Generically, they can be referred to as *nix:)

There are loads of versions of linux out there! The difference tends to be the number of packages that they have 'built in' if you like.

There's a huge list of versions here:


However, you probably want to stick with one of the mainstream installations such as RedHat or the like.

Ubuntu is becoming very popular as a desktop linux distribution, whereas the Red Hat Enterprise Linux is becoming very popular as a server. (So you don't have to pay huge licencing fees, you can have a look at a selection of the RHEL clones found here:


If you decide that you'd just like to have a look at what a distribution looks like without installing it, then some exist as 'liveCD' versions where you don't need to install onto your hard drive. There is a performance penalty, but it gives you the opportunity to have a look first. Knoppix is highly recommended in this area. Have a look at the selection:


If being indecisive about which one to download, then go to:


(one of the red hat clones) and download the version for your architecture 64bit/x86 etc.

Any skills you learn on this distribution can be considered as commercially valuable due to the growth of redhat servers in companies.

Yes, and no.

UNIXes (e.g. AIX, HP-UX, Solaris, Tru64, SunOS, et. al.) tend to be commercial products. As such, they tend to have licensing fees and/or restrictions attached to them. Of the UNIXes (or *NIXs) I mentioned, Solaris is about the only one that you can readily download for the X86 platform (http://www.sun.com)

"Linux" generally refers to a group of OSes built around the Linux kernel - examples include SUSE Linux, Mandriva, Debian, Red Hat, Slackware, et. al. Some are commercial, some are not. Most are readily available for download. They differ mainly in the selection of add-on packages that are wrapped around the Linux kernel.

UNIX came first (circa 30 years ago). Linux is designed to deliver a lot of the functionality of UNIX and came much later (circa 10 years ago).

If you're a *NIX newbie, I'd suggest getting a Linux as opposed to a UNIX. Its been my experience that SUSE Linux Professional (http://www.novell.com/products/suselinux/downloads) offers the most "Windoze-like" interface for new folx.
Linux is the more 'free' of the Unix varieties.

My recommendation is to first segregate OS by HD, and save a lot of grief concerning partitioing schemes. If you can, get an older computer to dedicate to linux for learning. Since it is less of a resource hog, it can ever run similar tasks on smaller, older units than MS OS can.

There are several distros, probably of those remaining you'd do best with RedHat or Novell.

Since you are a newbie, I think you are also better off ordering a CD with the latest distro, to get an idea of what it is supposed to look like, before you try to put it together yourself. Some game and book stores will sell you the CD, with a package of support an an application or two thrown in, such as for word processing or browsing the internet, etc. not to mention a choice of interfaces emulating Windows. So IMO you are better off building separately with one of those load & go CDs.

Without proper care (experience) you can otherwise trash a computer by mixing too many things in at a time.
Linux is a Unix like OS, it is NOT Unix.  To be called Unix you must pass a certification process and Linux will be the first to stand up and say "Linux is NOT Unix" and he has on several occasions.

That I am aware of the only free OS that is branded Unix is Solaris for x86.  However, I am not sure if Sun is still providing it free.

I am not sure if any of the BSD are certified as Unix.  If they are, then you have your choice of FreeBSD, NetBSD, and OpenBSD.  The BSD's will be closer to Unix than Linux will be.
<heh> how about SCO?

Yes, they are Unix favour.

Also, you can download Solaris x86 (for PC, free) from:

You can also download all the documentation installation, administration from:
You seems at very basic stage of *nix family.
The best option for you is Knoppix. Using it doesn't even need to install it.
Just insert the CD and OS runs fine in two minutes only.

Knoppix is the best solution for you. It is Live Linux from it's bootable CD.
1. runs from a Bootable CD and u need not to install it to HDD at all.
2. will be entirely loaded on RAM from it's CD.
3. booting takes only 3 minutes.
4. gives gives full GUI mode.
5. dynamically detects & installs all Drivers at runtime automatically. (Graphics, Sound, IDE, SATA etc.).
6. gives Read-Write access to HDD without installing on it.
7. supports FAT12, FAT16, FAT 32, NTFS, EXT2, EXT3 etc. File Systems.
8. gives your previous system untouched back after shutdown.(Does not write anything to HDD).
9. resets all configuration on each boot. (Does not get corrupted.)
