Thank you, angiehope. Your pointers to these summaries are helpful because they reinforce my initial impression: A good, thorough glob tutorial doesn't exist, so I'll have to write one for my colleagues. I even looked at several Unix books on Safari Books Online and couldn't find anything I'd call a tutorial on the topic. (There's a ring of hell reserved for those who squandered their mortal lives paraphrasing and abridging (plagiarizing) man pages for publication and profit.)

It's just as well because, to be truly effective, the tutorial must be verisimilar. The examples must be ones my colleages immediately recognize and see are useful and germane to the work they do.

Thanks!

Jim
