Linux / Unix User Essentials - 2 Days

Course Description

This course is designed with a very practical focus and encourages users to "work smarter not harder". It is intended for participants using Linux / Unix systems on a day-to-day basis but who are not involved in the administration of those systems. It covers the general operation of Linux / Unix systems using the command prompt. Even very experienced users of the windows operating system can feel lost when working in the rather alien environment of the Unix / Linux command line and this course will guide them to being competent and confident in this environment. Experienced users of the windows command prompt could also be missing out on many useful features of Linux / Unix as the two operating systems have quite different philosophies despite having many things in common.
