This page includes Bruce Barnett's tutorials on UNIX shell programming and various other arcane subjects of interest to wizards.

Note that I don't currently have a page on the bash shell because there is so much to cover. But the bash shell is a superset of the POSIX shell, so everything I have on this page applies to bash as well. Learn this first and get a gggood foundation on the basics that apply to nearly all shells.
For beginners, the first thing you should study is how and why quotation marks are so important, and how to use them. So I recommend my tutorial on Shell Quotes first.
Most of these tutorials were written from 1989 - to 1995 for The Sun Observer. But I have been keeping them up to date the best I can.
Over the years I strive to make the pages compliant with the validation engines.
