520			_aOperating system (OS) forms the interface between an end user and a system hardware. UNIX as an operating system remains the actual cost-free and user-friendly system hardware with regard to programming features. This text provides, in an easy-to-understand language, an in-depth analysis of various UNIX features supported as commands, highlighting their uniqueness and advantages in relation to Windows OS. The text begins with a brief account of what an operating system is. Then it goes to give the various general purpose UNIX commands and emergency commands with the command syntax. Besides, the text explores files and processes, the major building blocks of UNIX OS, their security features, and system calls. UNIX shell programming, vi editor––one of the powerful editors supported by UNIX OS––and communicating features and their commands are also dealt with at length. The book concludes with a discussion on file transfer, UNIX filters, PERL manipulation, administrator and networking commands.
