First question is how do you learn UNIX on a home lab. I understand that HP-UX isn't free and neither is SCO Unix and they don't run on x86 based systems anyways. The choices I believe are going to be OpenSolaris and FreeBSD. My question is UNIX commands the same across the board so if I learn to use OpenSolaris will I be able to use HP-UX (which is what I ideally want to learn).
Do all UNIX variants also have a GUI like OpenSolaris and FreeBSD or is say HP-UX command line based. I need some advice on the best course of action please.
Install it on its own system, don't try and dual-boot -- if that goes sour you could lose everything. You don't have to put it on a "good" system, even a junk PIII makes a good home-server if it has enough ram(512M or more). Then seriously use it. Do things like try to set up a file server, web server, get ssh going, and so forth. You may need to learn some basics first, like how UNIX manages file ownership and permissions and how partitions work in UNIX; these features at base are nearly the same everywhere, even if some have extended features like access control lists too.
You could also try and find an old HP-UX based system on Ebay. Sometimes you can get old hardware for a song.
There's a few kinds of BSD actually, and openBeOS, but close enough.
General-purpose commands will be nearly the same. They'll both have commands proscribed by POSIX like cp, mv, echo, and so forth, and they'll all have some variety of Bourne shell available. System configuration will be very different from OS to OS though. Also, different shells have different capabilities, but if you avoid features that aren't strictly Bourne shell features, like arrays, you should be able to write shell scripts that work in most shells. If you need these advanced features, the korn shell is more widely available than bash on most non-Linux systems.
At core nearly any UNIX system can be operated almost exclusively from the commandline -- even the heavily-GUI based Macintosh OSX. Most any UNIX can have some sort of GUI available, but this is frequently optional.
Cool sounds good. I have a server that has Windows 2008 R2 with Hyper-V installed on it so am going to use this to mess around with OS's that I normally don't deal with. I've always wanted to learn more about UNIX (and Linux) but never really knew what it was used for in the real world (probably with me having a Microsoft background :o). I think I will download FreeBSD and OpenSolaris and give them a whirl. Cheers for the help and gad I found this place.
I wouldn't mess with hyper-V. Getting networking working inside a virtual machine is going to be weird and very different from a real machine, for starters.
Unfortunately I can't dedicate hardware to one OS. I have installed 2 NIC's in the server so hopefully I should be able to setup networking ok. I've downloaded Solaris Express (which I believe is what used to be OpenSolaris and FreeBSD. Really appreciate the help. Coming from a pure MS background it might be a little strange using UNIX at first but these forums look great for help.
For the base knowledge, Unix and Linux are the same. the real question is what you want to do with it ?
Unix have a lot of variants : IBM-AIX, HP-UX, and (it's my opinion) the better is Solaris.
Linux is more flexible, redhat is the reference, but we have also Suse, Debian...
If you need to learn the basic knowledge, i think that Ubuntu or Mint are simple to use.
Good question and to be honest with my MS background I don't know what UNIX is used for in the real world. I assume it has many uses otherwise it wouldn't still be around. In a sense I would like to branch out my skills from Microsoft. I see some jobs in my area that require UNIX skills (sometimes only basic skills required) so I figure it's good to learn skills that are in demand.
I have downloaded CentOS with it being basically free Redhat and Solaris Express (since found that Open Indiana is the offshot of OpenSolaris so may download that instead) and FreeBSD. I'm going to install them over the weekend and have a mess on with them.
I've used Ubuntu in the past and think it's come on a long way but is probably too geared towards the home user. I have bought a book on CentOS so will get around to reading that soon. Going to look into buying a book on UNIX as well.
Unix-like OS are used for various purposes since it's quite versatile. ~92% of the TOP500 Supercomputers use Linux, Google uses it for it's webservers and spider/indexing farms, Home-/SoHo-NAS usually run an embedded version of Linux or BSD, as do some TVs and Access Points, ...
As far as I know, all unix/linux have command line. In our datacenter (I work for trading company), I never spotted any GUI on unix, only command line.
I'm learning with unixacademy dvds. It is all about command line. It comes with training and certification and I just passed two first exams. You can pick any edition you like (my favorite is fedora). It is effective and very inexpensive. I tried various books, but in my experience book reading is good for more advanced stages, when you mastered some basics.
Even though it has a server version I'd tend to agree. When people ask me for advice on it most of the time is spent fighting the autoconfigurators and a small fraction on making it do what you actually want it to do... Fedoracore, SuSe, and Gentoo are much less windows-like.
Great thread. This was some of the info I was looking for and some of the questions I didn't ask. I feel like a baby deer surounded by lions though, as far as my technical abilities and knowledge go. I have some old hardware that I'm going to download some version of UNIX on. still not sure which one..will have to do some more research first and then start playing around on it. I do have an old version of "UNIX for dummies...probably older than 2000 but should have some of the same commands taht I would need? I'll start playing around with that and get a little experience. Keep working on A+, network + just to get my foot int he door some place.
actually "for dummies" is not a bad book at all! I read it even before I had my hands on Linux and despite it didn't contribute to skill development, it was very good "pre-linux-unix" reading.
