This 4-day course is intended for people who:
Approximately 60% of the first day is lecture, as programming principles and procedures are introduced. About 40% of the second day is lecture and almost all of the third and fourth days are devoted to lab exercises. There are more exercises than most students can finish but the coursebook contains complete solutions to all exercises.
BTC can deliver this course at your site, for up to 8 students, for $5600, which includes instructor travel expenses.
You can also purchase the coursebook to be used as "self-paced" training. We provide the coursebook and a tar file containing files used for lab exercises. The coursebook contains lots of information (not just bulleted slides) and lots of lab exercises, as well as a Table of Contents and Alphabetic Index. The cost is $99. If you would also like up to 5 hours of email and phone support from the author of the course, the cost is $239, which includes the coursebook.
Each class can also be customized in content and length. For example, customers sometimes want a 5-day class which covers the basics of UNIX/Linux but also includes some shell programming techniques. We will work with you to determine what parts of this course and our UNIX/Linux Fundamentals course to combine that will fit in five days.
