You can read all the books you want, but until you setup a machine and break it a few times, you don't really get a feel for it.
There are plenty of different unix boxes and yes some are hardware dependent e.g. SPARC, but Free/Net/OpenBSD are all unices and run on x86-class [as well as many other] processors. Linux is unix-like, but not really unix, you wont learn anything from Ubuntu. Personally I love FreeBSD as far as unix goes.
Ubuntu doesn't let you do anything. If you actually want to learn linux, start with something that lets you learn, e.g. Slackware or Gentoo. If you want to learn unix, use FreeBSD. They are all usable without any experience as long as you are willing to use google and have some patience.
We run SCO Unix on all kinds of x86 machines, from paperweights like Pentium 75's running VERY old versions of Xenix (google that one!) to modern P4 3Ghz+ machines running Unixware (a Linux-like environment, but still a Unix System V derivative at heart).
Two weeks is short, but you can at least get a working knowledge in that timeframe. Good luck!
No, FreeBSD is unix, well atleast a derivitive of it. Bell labs owns the unix copyright
FreeBSD® is an advanced operating system for x86 compatible (including Pentium® and Athlon™), amd64 compatible (including Opteron™, Athlon 64, and EM64T), UltraSPARC®, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX® developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
