This DOS Guide contains the use and syntax of 71 commands and 8 DOS utilities. I used to host this DOS guide ten years ago on my website, but removed it when I migrated from static HTML pages to using PHP. I had assumed that there would not be a demand for a DOS guide, but I was wrong.

So I have brought the DOS Guide back. Currently, it is hosted outside of my website, but I am working on migrating the DOS Guide back into my website. Until I am done, you can access the DOS Guide here: The DOS Guide

Update

the DOS guide on my site covers  basic DOS commands. If you don’t find what you need on my site, take a look at Computer Hope’s DOS guide
