Tutorials and Other Handouts
I've written several primers as supplements to courses I've taught. They're here for the taking.
A DOSshell primer. DOSshell is not a fun scripting language, but it's sometimes helpful to know. The primer is not as complete as some websites, but it's here for the taking. Word 2000 format.
It's not about the GUI: a Command-Line-Based Introduction to the UNIX Environment. I've been working on this tutorial sporadically since 1992. It's not as complete as the O'Reilly materials, but it's reasonably good, and it's free. Word 2000 format. Last update: July 2004.
A Cisco 2924 XL Switch Primer. A work in progress. Reasonably complete up through basic material on Cisco's IOS and single-switch VLAN management.
