UNDERSTANDING UNIX
Author: K. SRIRENGAN
language: en
Publisher: PHI Learning Pvt. Ltd.
Release Date: 1998-01-01
This compact and practice-oriented text covers features of UNIX as an operating system and classifies the entire UNIX commands into 15 categories. Separate chapters are devoted to essential commands for: interacting with UNIX, handling files and directories, security, mail and remote communication, UNIX enhancement, and system administration under SCO UNIX followed by troubleshooting hints for super users.There is an exhaustive coverage for system administration of UNIX system, generally available under all versions and releases of UNIX, particularly from AT & T UNIX to system V release 3.0.The book is ideally suited for the undergraduate and diploma level students of computer science and computer application courses.
A Quarter Century of UNIX
Author: Peter H. Salus
language: en
Publisher: Addison-Wesley Professional
Release Date: 1994
Based on interviews with the key software engineers who invented and built the powerful UNIX operating system, this book provides unique insight into the operating system that dominates the modern computing environment. Originating from a small project in a backroom at AT &T Bell Labs, UNIX has grown to be a dominant operating system in the commercial computing world -the operating system responsible for the development of the C programming language and the modern networked environment. Peter Salus is a longtime and well-recognized promoter and spokesman for UNIX and the UNIX community.
Real-Time UNIX® Systems
Author: Borko Furht
language: en
Publisher: Springer Science & Business Media
Release Date: 2012-12-06
A growing concern of mine has been the unrealistic expectations for new computer-related technologies introduced into all kinds of organizations. Unrealistic expectations lead to disappointment, and a schizophrenic approach to the introduction of new technologies. The UNIX and real-time UNIX operating system technologies are major examples of emerging technologies with great potential benefits but unrealistic expectations. Users want to use UNIX as a common operating system throughout large segments of their organizations. A common operating system would decrease software costs by helping to provide portability and interoperability between computer systems in today's multivendor environments. Users would be able to more easily purchase new equipment and technologies and cost-effectively reuse their applications. And they could more easily connect heterogeneous equipment in different departments without having to constantly write and rewrite interfaces. On the other hand, many users in various organizations do not understand the ramifications of general-purpose versus real-time UNIX. Users tend to think of "real-time" as a way to handle exotic heart-monitoring or robotics systems. Then these users use UNIX for transaction processing and office applications and complain about its performance, robustness, and reliability. Unfortunately, the users don't realize that real-time capabilities added to UNIX can provide better performance, robustness and reliability for these non-real-time applications. Many other vendors and users do realize this, however. There are indications even now that general-purpose UNIX will go away as a separate entity. It will be replaced by a real-time UNIX. General-purpose UNIX will exist only as a subset of real-time UNIX.
