unix和c语言之父写的通俗易懂的论文,介绍unix操作系统的基本原理,好书只送有缘人,不多解释.

Since PDP-11 Unix became operational in February, 1971, over 600 installations have been put into service. Most of them are engaged in applications such as computer science education, the preparation and formatting of documents and other textual material, the collection and processing of trouble data from various switching machines within the Bell System, and recording and checking telephone service orders. Our own installation is used mainly for research in operating systems, languages, computer networks, and other topics in computer science, and also for document preparation.

希望搜到The UNIX Time-Sharing System中文版，但搜了一中午也没有搜到，自己努力，将英文的翻译为中文，供大家学习之用。由于英文差，难免有错误的地方，见谅了。
