Editor's note: After Daniel J. Barrett finished writing the Linux Pocket Guide, O'Reilly's latest offering in its pocket series, the marketing folks said, wait, hold on, we have one more thing we'd like you to do. That one more thing turned out to be the "Linux Quick Reference to Useful Commands," Daniel's hand-selected list of the most essential Linux commands and the tasks they perform.
We are presenting this quick reference as a PDF download. The file size is a little over 100KB. It's just the type of reference -- like the Linux Pocket Guide itself -- that you will want to keep right by your keyboard for those times when you need a fast, useful answer to a problem. Download the "Linux Quick Reference to Useful Commands."
And if you're looking for yet another useful reference to Linux commands, be sure to check out the Linux Command Directory -- a comprehensive list of 379 commands, their descriptions, and available options -- derived from O'Reilly's Linux in a Nutshell, 3rd Edition.
Daniel J. Barrett has been immersed in Internet technology since 1985. Currently, he is working as a software engineer. He is the author of O'Reilly's Linux Pocket Guide, and the coauthor of two more O'Reilly books: Linux Security Cookbook, and SSH, The Secure Shell: The Definitive Guide.
