UNIXTM C SHELL FOR
PROGRAMMERS

SYNOPSIS

"UNIXTM C Shell for Programmers" is designed for programmersand systems managers who wish to learn UNIXTM and the C shell on PC's runningXENIX or VP/IX, or larger machines running DEC Ultrix, Berkeley 4.XBSD andSUN OS workstations. This course focuses on those aspects of UNIXTM andthe shell that provide the tools to develop software and maintain systems.

ELIGIBILITY REQUIREMENTS

Familiarity with another operating system (VMS, DOS, etc.) is helpful,but not mandatory.

LEARNING OBJECTIVES

The principal objective of this course is to provide each student withthe understanding of how to use UNIXTM and the C shell to develop and supportsoftware. Specific learning objectives for this course are:

• to understand how the different versions of UNIXTM in the marketplace fit in with Berkeley UNIXTM and the compatibilities between the machines they run on;
  
• to acquire the skills to manipulate files and directories within the UNIXTM filesystem;
  
• to become proficient with the C shell, both as a command interpreter and as a programming language;
  
• to learn how to customize your working environment with command aliases, setup files and job control; and
  
• to learn how to write custom tools and install them in the UNIXTM environment.

COURSE DESCRIPTION

UNIXTM has attracted widespread interest throughout the computing industryas a portable and practical operating system for the development of software.With over 200 online utilities, networking, electronic mail, and a programmableshell, programmers can quickly design tools to develop and maintain software.As one of the major software engineering developments of the 1980's, UNIXTMenjoys the reputation of an operating system of great flexibility, eleganceand power on systems ranging from 16 and 32-bit microcomputers and workstationsto mainframes.

This course is designed to present practical concepts and applicationsto those students who wish to learn Berkeley UNIXTM and the C shell. Studentsexplore unique aspects if the UNIXTM system and the C shell, such as pipes,filters, I/O redirection, aliases, and job control. Hands-on workshops augmentthe lecture material. Students completing the course will have an extraordinarycommand of the interactive use of UNIXTM commands and the shell.
