> Unix v. Solaris
Solaris is Sun Microsystems implementation of the Unix standard, with their own enhancements. IMHO, it's close to the Unix "standard"

> Unix v. Linux
Linux is a "unix-like" operating system; For all intents and purposes, you can regard it as yet another version of Unix. Linux is Open Source (free to copy/use) and there are many slightly different versions, all with their own enhancements.

99% of what you learn using Linux or Solaris will work on another Unix flavour.  Whan you get into programming or system administration, you'll find more differences between flavours, but the same priciples still apply.

tfewster has given you some good infor.

You can download free *nix:

     Solaris x86 (Intel): http://wwws.sun.com/software/solaris/binaries/get.html
     OpenBSD http://www.openbsd.org/
     NetBSD http://www.netbsd.org/
     FreeBSD http://www.freebsd.org/
     Linux: http://www.linux.org/
     
     As a end user or programmer most of the Linux/Solaris commands can work on
another *nix flavour, as a sys adm, there are something different between each *nix
favour.

    To learn Unix, have a look at :

Of all of the flavors available (Solaris x86, FreeBSD, etc) - my opinion is that the best "unix" to download for free are any of the variants of LINUX.   Here, you will find the most available information (for example, "howto" articles).

Since it appears you are learning Unix from the get-go, I have two suggestions:

One:   A really good place to contrast and compare linux distributrions is http://distrowatch.com

Two:  An even better thing I highly recommend for you is to download and boot up a "live cd" version of Linux.  

What is live-cd?  It's a means of distributing a linux distribution on a single, bootable CD that DOES NOT HAVE TO BE INSTALLED.    You pop the CD in, boot, and voila!  You're running Linux.   Shutdown, remove CD, reboot- your PC is back the way it was- UNTOUCHED.   It's totally safe, and a means to experiment, without all the headaches and steep learning curve of setting up a dual-boot system, and so on.    My highest recommendation is to check out http://knoppix.org.   (after you get there, be sure to click on the AMerican Flag to get the ENGLISH text!).

Lastly, you asked about common unix commands.    Unix systems have graphical tools of course, but the command-line still remains the most powerful.

Here are some SIMPLE Unix commands to get you started.

Command     Purpose

ls                 "list" files (show directory contents)
pwd             Print current directory - "where you are"
cd                "change directory".  Works more or less likes it's DOS cousin
cp                copy.    cp <file1> <file2>
mv               "move", or rename.   mv <file1> <file2>
exit              end process (or logout)
who             Show who else is logged on
ps                Show running processes
man            *manual*.  i.e., "help".   For example, type "man ps" to see how the PS command works.

I hope this helps.   Download knoppix--- boot it, play around.   Learn, without mucking with your PC at ALL.
