Description

This lecture/lab course teaches computer users to make productive use of the UNIX® operating system (OS). The most important and empowering concepts, such as pattern matching, command editing, shell scripting, and pipelines are emphasized, alongside coverage of basic OS utilities and services.

Because UNIX can be somewhat confusing for new users, many typical mistakes are illustrated, and students are shown how to avoid them ("forewarned is forearmed"). Fully 40% of class time is spent in supervised laboratory activities, with students using a Korn (POSIX) shell interface to UNIX.

Although this is intended as a first course in UNIX, it does cover elementary shell programming, and is therefore especially well suited for those with a logical mindset who wish to become "power users", Programmers, or System-, Database-, Network-, or Web-Administrators.

Although the course material is applicable to all UNIX and UNIX-like systems, we also have a LINUX version of this course, for those who prefer that emphasis.

Prerequisites

A conceptual understanding of elementary computer terms, such as memory, disk storage, and time-sharing is required. Typing skills are beneficial, as is familiarity with other operating systems, such as DOS.

Author

Dr. Tim Maher has been an avid user of UNIX since 1976, and, since the early 80s, he has taught literally thousands of others to make the most of it. He has authored 16 UNIX courses, including ones taught by AT&T.

CONSULTIX instructors are renowned for their ability to communicate complex concepts in simple terms and to make the study of dry technical material enjoyable.
