Part 1: Fundamentals of the UNIX System

   

---

The first part is an introduction to the UNIX system. This is a more-general UNIX part and consists of login and logout procedure, file and directory manipulation, file editing, an introduction to the POSIX shell, and file security/permissions. This part shows the concepts of users and groups, which are common to all UNIX systems. UNIX commands related to all these topics are presented and the more commonly used options of these commands are discussed. This part also throws light on standard input/output and I/O redirection. Chapters 10 and 11 introduce shell programming concepts. Here you will find a number of shell programs, up to elaborate shell variables and flow control structures.
