>That question used to be asked a lot, four or five years ago. But, as things have progress, Linux has swept the Unix world by storm and now the question is: "Does that version of Unix run Linux apps?" IMO, it is only a matter of time before Linux replaces all versions of Unix.


IBM certainly seems to be more interested in selling Linux than AIX though I don't completely understand why. There is a funny TV ad for IBM Linux servers where a manager thinks that an entire roomfull of servers has been stolen. Actually, they have all been replaced by a single IBM mainframe running Linux.

Is Linux Unix? Seems like a moot question. Richard Stallman believed it was important to claim that GNU which predated Linux is not Unix. GNU = Gnu's Not Unix.

I'm sure this was just to avoid royalty issues.

I don't think there is any major technical reason to claim that Linux is not Unix.
