    Ok. There is no "LINUX" to be ever seen. Linus Torvold made something called Linux, which at heart is Unix. Unix is for servers. Linux is for users. Starter platforms of *Nix can be found at Ubuntu and Unix must be purchased I believe..

    Unix is mostly commercial. The open source flavors of unix are BSD and Solaris. There might be others.

    Linux is "unix like" but it is not unix. They are as different as mac OS and windows. There are some apps that are "binary compatible" because they use POSIX.

    YAD is right though - unix is mostly used for servers. The only vaguely usable UNIX (excepting Mac OS of course) is Solaris, and you need killa hardware for that and you are very limited to your selection of desktop apps.

    What are you trying to accomplish? As always, the real test is "Is this the best tool for the task?"

    if you're a beginner looking to get into *nix, go with linux, and a distro that has a large and beginner-friendly community. As of today, I'd suggest starting with Ubuntu and the Ubuntu forums.

    Ubuntu is now permanently installed on my laptop(for 2 weeks or so now), but I have no intention of learning much about it. It just works and that makes me happy ;) Though the Synaptic Package Manager makes things real nice when I wanna specific program for something, or even a game. But of course you won't find Dreamweaver or World of Warcraft on there, only similar things made by other people.

    Most usual reason that you can't get to a home directory is that, that directory got deleted or the permissions on it got changed.

    One other very popular business version of Unix is AIX unix which is the default OS IBM uses for it's Unix servers.

    If the permissions were changed you will have to use chmod. If the owner was changed you will have to use chown. If they were deleted you would need to restore them from your nightly backup.

    depending on the setup, home dirs can be a mounted dir too (nfs or a disk mount, or other).

    If you're not running the 'nix server at work, and you don't know why you can't mount your homedir, you won't have permissions to fix it. :)
