This course provides training on standard UNIX/Linux commands and utilities used for day to day tasks including file manipulation, program execution and control, and effective use of the shell and desktop environments. The course presents the concepts necessary to understand the way UNIX works as well as the system's most commonly used commands. Data manipulation utilities and shell syntax for synthesizing command pipelines are emphasized. Bourne shell, Bash shell and Korn shell programming techniques are introduced so students will be able to read and modify existing shell scripts as well as create their own. Desktop environments are also introduced from a user's perspective, including common window managers, Open Office utilities and an introduction to configuration tools. Comprehensive exercises are integrated throughout to reinforce learning and develop real competency.

By the end of this course, delegates will know about:

 

• Command Syntax
• Controlling Processes
• Using the File System
• Shell Syntax
• Data Manipulation Utilities
• Controlling Your Environment
• Shell Scripting
• Using Desktop Environments

Network system administrators network engineers, IT personnel, directors & managers, company advisors, corporate finance officers & strategic planners, accounting personnel & corporate officers, commercial and investment bankers
