Hi,

    I vote for doing real things with Linux. I have been worked with many flavors of Unix and Unix look-a-likes over the years. From the perspective of an OS kernel developer Unix and Linux are quite different, but from the perspective of an applications programmer or user there are only a few areas that are significantly different if you install Linux straight out of the box. These two areas are: the shell and the x-windows interface.

    Linux uses the bash shell and Unix uses the Korn shell. But, you can get a public domain version of the Korn shell that runs on Linux. I am sure that someone will respond and say that the command line switches for some popular commands are not the same when using Linux and Unix. My response is that quite often the switches for these commands vary from Unix implementation to Unix implementation. (I do find that having to remember to use ps -ef as opposed to ps -af is a pain, but not a very big one.)

    Linux uses X86 and whatever window manager(s) the vendors choose to provide. Unix uses X86 with the Motif window manager (I think you might still be able to get Open Look on Sun -- but I'm not sure). If you really want Motif you can buy a Motif look-a-like, but the differences between the window managers are trivial. I am sure that everyone whose career or hobby is the development of window manager software will take umbrage at this thought, but I am trying to look at things from the perspective of someone who wants to pick up enough practical experience to be able to walk into a Unix shop, get a job, keep it, and grow.

regards

Jerry Gitomer
