Multi-Vendor UNIX Fundamentals

Multi-Vendor UNIX Fundamentals course will provide the delegates with transferable skills, and - equally important - will give them appreciation of working in a multi-vendor UNIX environment. The course concentrates on the common approach to the variants of UNIX whilst looking at some specific areas of particular systems and shells. The platform used for practical exercises is Linux, with SSH access provided to at least one other version of UNIX, for example HP-UX.

The course explains how to use the basic facilities of a UNIX system and demystifies most of the major concepts and principles of UNIX operation. We discuss the role the shell plays in interfacing with the operating system, analyse the file system and explore file, directory and data manipulation utilities.

We also take a look at more advanced use of the shell, including a brief introduction to shell scripts (command or batch files) and how to use them to automate repetitive tasks. There is a very useful overview of simple UNIX system administration and network communication utilities.

Target Audience:

This course is aimed at IT professionals wanting to become proficient in using a UNIX platform in a multi-vendor environment. It is also recommended for users of any UNIX system who need to 'escape' an application and use the system at the command line level.

Learning Objectives

Hands-on work (labs, demos and interactive exercises) accounts for nearly half of the course. Each lab session is carefully structured to lead you through the concepts of the preceding chapter, thereby building knowledge and confidence in using UNIX. Each delegate is assigned his/her own machine, and all machines are configured as a network.

Pre-Requisites

No specific UNIX knowledge is required, but delegates must have a basic knowledge of the major computer components as well as computer operating system functionality and concepts.

Ability of working with command line (such as in DOS or VMS) and familiarity with hierarchical file structure, organisation and management is assumed.
