Updating Our Linux Subjects - Summer 2012

The Linux subjects consist of the following:

  • ULI101 - Introduction to Unix/Linux and the Internet
  • OPS235 - Introduction to Open System Servers
  • OPS335 - Open System Application Server
  • OPS435 - Open System Automation
  • OPS535 - Open System Application Server

Currently, very little BASH scripting is taught in each of ULI101, OPS235, OPS335 and OPS535. OPS435, on the other hand, focuses 100% on BASH programming. The drawback with this configuration is that students must learn BASH in one semester. A better configuration would be to spread BASH programming over the 5 subjects. This would provide continuity over 5 semesters not just for BASH programming but for system administration content as well - since OPS435 would now have a large component of system administration activities as well as some BASH programming.

Each of the 5 subjects would require a BASH scripting component. Below is a first pass at fleshing out what BASH concepts/commands need to be taught in each of the courses. Feel free to add your own ideas.
