A couple years ago, I pitched the idea of a Linux/UNIX training course to a few people at work. I thought that this was a growth area for training, especially considering how many companies and clients in the area were migrating to or evaluating the use of Linux for servers. Unfortunately, before I could put together a good syllabus and advance the proposal, I was sent to Fifth-Third’s basement as a novice ClearCase administrator.

Recently, an email from a training placement company landed in my dead spam-filled old mailbox, and I noticed it contained a reasonable UNIX training syllabus, reminding me of my old plans. Below is a revised edition of the Linux/UNIX training course that I once wanted to create and teach.
