我也刚接触UNIX不久，讲的不对的地方还请大家指正
1. IBM: AIX
AIX stands for Advanced Interactive Executor, 是IBM 主打的UNIX 操作系统，相对于其它的系统，AIX可以算是比较年轻的产品了。主要运行于RS/6000 和 SP 等机型。AIX 继承了 AT&T's System V UNIX and BSD (Berkeley Standard Distribution) UNIX 的系统，其特点主要体现于高功能的图像和浮点运算。最近刚听朋友说AIX 的 founder 竟然是中国人，不久前还在上海开了一家公司。姑且不论真假，全当是对国人的一种鼓励吧。
2．Sun Microsystems: Sun OS, Solaris
最早由BSD 4.x 演变而来的Sun OS 是较老的基于text-based 的UNIX 系统，只能运行于Sparc 的芯片上。（没有GUI 哦，现在应该很少有人用了吧）
Solaris,（感觉上这个知名度最高了）。其实Solaris 是 Sun OS 的增强版，主要添加了图形界面和网页浏览器等桌面工具。Solaris 可以运行于Sparc, Intel, Cyrix 和 AMD 的处理器上, 这也可以说是Solaris 之所以受欢迎的原因之一吧。从2.5 以后的 Solaris 版本可以支持64位的运算处理器，并且通过使用Ultra-Creator graphics，能对2D 和 3D 的图形应用进行很好的支持。本月15 日刚刚公布的Solaris 10 ,相信也一定会对UNIX 众多操作系统的市场形成另一轮的冲击。
3．Hewlett-Packard: OSF, Digital UNIX, Tru64, HP-UX
其实OSF（Open Software Foundation）和Digital UNIX 都不是HP 的产品，而是属于DEC (Digital Equipment Corporation)的。DEC公司可以说是UNIX 领域的先驱者，早在UNIX 还在贝尔实验室里开发的阶段，DEC PDP-7 就成为少数的可以运行UNIX的机型之一，之后DEC又相继开发了其自己的VMS操作系统。只是因为经营不利，于98年被Compaq收购，之后又归并与HP的旗下。而OSF 也相继被改名为Digital UNIX, 和现今的Tru64. 如果你对DEC的兴衰史感兴趣的话不妨看看下面的文章（顺便练练英语哦）
http://en.wikipedia.org/wiki/Digital_Equipment_Corporation
HP-UX才是真正惠普自己的产品（看名字就知道了哦）。它在很大程度上是基于System V的构造，适用于HP PA-RISC, HP Focus , 和Motorola 680x0等机型。不知道是出于嫉妒还是什么原因，HP现今总是鼓励它原有的Digital Unix 的客户转型去用HP-UX,哈哈毕竟是自己的产品好啊。不过个人认为Digital UNIX 在64位处理器上还是比其他操作系统占据一定的优势的。
4．SCO: Xenix, Uniware
SCO于95年向novell公司分别购买了UNIX System source technology business和 Uniware2个人不怎么喜欢这家公司，感觉上老是自己不好好的做自己的东西。加之近来又与IBM官司缠身，看来是就快不行了。
5．SGI: IRIX
IRIX 是运行于SGI MIPS机型上的UNIX系统。对它不太了解，不过样
样子挺好看的，像个speaker一样。
其它的一些只是在公司里看到过，没有什么具体的接触，所以希望大家来补充。顺便说一句，也不要忽略了Linux嘛，其实在商务应用里像Redhat ER 这样的产品还是有一定的市场竞争力的（毕竟便宜嘛）。如果有人对distributed-systems感兴趣的话，我很愿意和大家交流，在这里我先留下msn: leonardgu@hotmail.com . 最后来一张UNIX & LINUX的发展表，大多数的系统上面都提及了，希望对你有用吧。
1957 Bell Labs found they needed an operating system for their computer center which at the time was running various batch jobs. The BESYS operating system was created at Bell Labs to deal with these needs.
1965 Bell Labs was adopting third generation computer equipment and decided to join forces with General Electric and MIT to create Multics (Multiplexed Information and Computing Service).
1969 By April 1969, AT&T made a decision to withdraw Multics and go with GECOS. When Multics was withdrawn Ken Thompson and Dennis Ritchie needed to rewrite an operating system in order to play space travel on another smaller machine (a DEC PDP-7 [Programmed Data Processor 4K memory for user programs). The result was a system which a punning colleague called UNICS (UNiplexed Information and Computing Service)--an 'emasculated Multics'.
1969 Summer 1969 UNIX was developed.

The main thing missing was pipes.

1. IBM: AIX
AIX stands for Advanced Interactive Executor, 是IBM 主打的UNIX 操作系统，相对于其它的系统，AIX可以算是比较年轻的产品了。主要运行于RS/6000 和 SP 等机型。AIX 继承了 AT&T's System V UNIX and BSD (Berkeley Standard Distribution) UNIX 的系统，其特点主要体现于高功能的图像和浮点运算。最近刚听朋友说AIX 的 founder 竟然是中国人，不久前还在上海开了一家公司。姑且不论真假，全当是对国人的一种鼓励吧。
2．Sun Microsystems: Sun OS, Solaris
最早由BSD 4.x 演变而来的Sun OS 是较老的基于text-based 的UNIX 系统，只能运行于Sparc 的芯片上。（没有GUI 哦，现在应该很少有人用了吧）
Solaris,（感觉上这个知名度最高了）。其实Solaris 是 Sun OS 的增强版，主要添加了图形界面和网页浏览器等桌面工具。Solaris 可以运行于Sparc, Intel, Cyrix 和 AMD 的处理器上, 这也可以说是Solaris 之所以受欢迎的原因之一吧。从2.5 以后的 Solaris 版本可以支持64位的运算处理器，并且通过使用Ultra-Creator graphics，能对2D 和 3D 的图形应用进行很好的支持。本月15 日刚刚公布的Solaris 10 ,相信也一定会对UNIX 众多操作系统的市场形成另一轮的冲击。
3．Hewlett-Packard: OSF, Digital UNIX, Tru64, HP-UX
其实OSF（Open Software Foundation）和Digital UNIX 都不是HP 的产品，而是属于DEC (Digital Equipment Corporation)的。DEC公司可以说是UNIX 领域的先驱者，早在UNIX 还在贝尔实验室里开发的阶段，DEC PDP-7 就成为少数的可以运行UNIX的机型之一，之后DEC又相继开发了其自己的VMS操作系统。只是因为经营不利，于98年被Compaq收购，之后又归并与HP的旗下。而OSF 也相继被改名为Digital UNIX, 和现今的Tru64. 如果你对DEC的兴衰史感兴趣的话不妨看看下面的文章（顺便练练英语哦）
http://en.wikipedia.org/wiki/Digital_Equipment_Corporation
HP-UX才是真正惠普自己的产品（看名字就知道了哦）。它在很大程度上是基于System V的构造，适用于HP PA-RISC, HP Focus , 和Motorola 680x0等机型。不知道是出于嫉妒还是什么原因，HP现今总是鼓励它原有的Digital Unix 的客户转型去用HP-UX,哈哈毕竟是自己的产品好啊。不过个人认为Digital UNIX 在64位处理器上还是比其他操作系统占据一定的优势的。
4．SCO: Xenix, Uniware
SCO于95年向novell公司分别购买了UNIX System source technology business和 Uniware2个人不怎么喜欢这家公司，感觉上老是自己不好好的做自己的东西。加之近来又与IBM官司缠身，看来是就快不行了。
5．SGI: IRIX
IRIX 是运行于SGI MIPS机型上的UNIX系统。对它不太了解，不过样
样子挺好看的，像个speaker一样。
其它的一些只是在公司里看到过，没有什么具体的接触，所以希望大家来补充。顺便说一句，也不要忽略了Linux嘛，其实在商务应用里像Redhat ER 这样的产品还是有一定的市场竞争力的（毕竟便宜嘛）。如果有人对distributed-systems感兴趣的话，我很愿意和大家交流，在这里我先留下msn: leonardgu@hotmail.com . 最后来一张UNIX & LINUX的发展表，大多数的系统上面都提及了，希望对你有用吧。
1957 Bell Labs found they needed an operating system for their computer center which at the time was running various batch jobs. The BESYS operating system was created at Bell Labs to deal with these needs.
1965 Bell Labs was adopting third generation computer equipment and decided to join forces with General Electric and MIT to create Multics (Multiplexed Information and Computing Service).
1969 By April 1969, AT&T made a decision to withdraw Multics and go with GECOS. When Multics was withdrawn Ken Thompson and Dennis Ritchie needed to rewrite an operating system in order to play space travel on another smaller machine (a DEC PDP-7 [Programmed Data Processor 4K memory for user programs). The result was a system which a punning colleague called UNICS (UNiplexed Information and Computing Service)--an 'emasculated Multics'.
1969 Summer 1969 UNIX was developed.
1969 Linus Torvalds is born.
1971 First edition of UNIX released 11/03/1971. The first edition of the "UNIX PROGRAMMER'S MANUAL [by] K. Thompson [and] D. M. Ritchie" is also dated "November 3, 1971". It includes over 60 commands like: b (compile B program); boot (reboot system); cat (concatenate files); chdir (change working directory); chmod (change access mode); chown (change owner); cp (copy file); ls (list directory contents); mv (move or rename file); roff (run off text); wc (get word count); who (who is one the system). The main thing missing was pipes.
1972 Second edition of UNIX released 12/06/1972
1972 Ritchie rewrote B and called the new language C.
