My twitter handle is @grymoire and I will gladly try to answer questions.

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.

Here's the directory containing all of my scripts

Background

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.

I'd give you my e-mail address, but frankly I think spammers should rot in hell. Therefore I'll give you my e-mail address in longhand form.

The username is - tutorials
Put them together with an at sign between and you can reach me. An example might be username@domain or abuse@fbi.gov - notice the spambait.

Thanks to "Jesse Silverman" for some corrections.
