UNIX Introduction

About the course
Unix offers business a highly stable, scalable and completely configurable environment on which to build applications. Nothing is hidden. Everything is manageable. This means complexity, rather than being hidden as in Microsoft operating systems, has to be understood and dealt with by those involved with supporting, or building, Unix systems.
Commands entered into the terminal interface are not self-evident, as is the case with a GUI (Graphical User Interface). We address these issues as part of the training and it is our intention that you should feel comfortable moving forwards with Unix at the end of the course. All exercises and demonstrations are of a very simple nature, the objective being to build confidence, rather than to dazzle the user.
Sun Microsystems Solaris Unix operating system is our delivery platform and the Korn shell is the command shell environment. However, anything you learn on the Sun platform can be immediately implemented on AIX, HP/UX, or other vendor’s Unix operating system, so delegates from all sites will benefit from the training. Should you require the ‘C’ shell or other shell in the work place, the K shell may be considered to be a good foundation, but please note that there are certain differences between shells.

Audience

If you need to learn Unix then this course is a great starting point. Typically our delegates come from these environments:-

Career change, seeking to move into a workplace requiring Unix skills
Migrating from NT platforms to Unix and need to make the change
Moving from mainframe to Unix operating systems
Planning a career as a programmer in a Unix environment
Building job packs for 3rd party application products
A suitable precursor to our Systems Administration course

Prerequisites
Familiarity with any other operating system is helpful, though not essential eg NT, DOS, MVS/XA. A logical approach to IT, a calm approach and perseverance are all that is required in addition. The course is conducted using the terminal line input interface and you should feel comfortable typing commands into a non-GUI monitor.
