you mean the UNIX OS?

you cant just download it as it is propieratary e.g HP/UX or AIX

If you want a free system that is very like UNIX then take a look at FreeBSD

and no, we're not here at your beg and call to answer your questions immediately.

Your tone is extremely rude, suggesting you're more important than anyone else in the world.

yeah i tried free bsd , thanks!!

opensolaris is a pain for first time unixeres and has high requirements

yes but why not go with linux!

because he said unix, as the name says, GNU/Linux is not Unix

>because he said unix, as the name says, GNU/Linux is not Unix
Neither is FreeBSD, OpenSolaris, etc.. They're all clones of the original Unix creations, which are now dead.

FreeBSD is just used as a popular alternative to Unix because it's more pure (one distribution pretty well), gives a close feel to the original Unices, and has less restrictive licences for commercial software than Linux. Technically however, FreeBSD has the same relationship to Unix as Linux does to Unix.

AFAIK the BSD branch was derived straight from Unix, while GNU was a rewritten Unix-like independent development originally by LT
