哪有unix下载呢　谢谢

什么UNIX？AIX、IRIX还是...

楼主连UNIX为何物均不知也要下载么？
我只知道只有一个Solaris for x86能装在x86机器上，其他的UNIX如果可以楼下的兄弟可以告知。

4 x86的目前只有Solaris和FreeBSD(OpenBSD和NetBSD,反正BSD家族)两种。

啧啧啧……No！所有4.4BSD-based系统(也就是FreeBSD、NetBSD、OpenBSD等)都是UNIX-like而非UNIX，除了能在它们官方主页找到相关信息，还有一个根本的区别就是被成为UNIX的那是商业系统，如果没有注册The Open Group的商标，就是UNIX-like。

讨论到早期UNIX形成时的历史了，就因为你说的原因托瓦兹说：The linux not UNIX!
所以UNIX-like问题比较难说，但是BSD确实是UNIX的鼻祖，BSD team却是一个学术团体。

BSD UNIX确实是啊，我没说不是，但是这段历史你可以阅读一下《FreeBSD Handbook》就知道了，三大BSD早就不是当初那个BSD UNIX了

http://www.openbsd.org

The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX.

http://www.netbsd.org

NetBSD is a free, secure, and highly portable UNIX-like Open Source operating system available for many platforms, from 64-bit AlphaServers and desktop systems  to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and it is user-supported with complete source. Many applications are easily available through The NetBSD Packages Collection.

FreeBSD项目官方站点首页我没看到FreeBSD到底是UNIX还是UNIX-like，但是可以搜索

http://www.freebsd.org/docproj/docproj.html

In addition, FreeBSD will be the first exposure to a Unix-like operating system for many of its users, so the availability of high quality, accurate documentation is paramount.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/users-groups.html

A group is simply a list of users. Groups are identified by their group name and GID (Group ID). In FreeBSD (and most other UNIX like systems), the two factors the kernel uses to decide whether a process is allowed to do something is its user ID and list of groups it belongs to. Unlike a user ID, a process has a list of groups associated with it. You may hear some things refer to the ``group ID'' of a user or process; most of the time, this just means the first group in the list.

http://www.freebsd.org/doc/en_US.ISO8859-1/articles/explaining-bsd/x117.html

So what is really the difference between, say, Debian Linux and FreeBSD? For the average user, the difference is surprisingly small: Both are UNIX like operating systems. Both are developed by non-commercial projects (this does not apply to many other Linux distributions, of course). In the following section, we will look at BSD and compare it to Linux. The description applies most closely to FreeBSD, which accounts for an estimated 80% of the BSD installations, but the differences from NetBSD and OpenBSD are small.

我想现在不是那么难说了吧？

是喽，你是对的。
