I have completed reviewing the proofs for the 2nd Edition of my Using and Administering Linux: Zero to SysAdmin self-study training series. This is the last bit of my involvement and all three books are nearly ready for the printers.
Each book has an extensive index that is the most complete I’ve ever seen. This is quite intentional as I think its important to be able to find topics easily in a book that is intended to be a reference as well as a self-study course. I have fixed all of the known errata from the 1st Edition and brought it up to date with Fedora 37 and 38. With new chapters for systemd, NetworkManager, Ansible, and the BTRFS filesystem, this series is the most complete ever published.
Book Signing at ATO
I will be at All Things Open again this year to present a talk on Bash Configuration and Usage, and to do a book signing. I hope to have all three of these books available as well as a few copies of my other two books as well. Due to limited supplies we can provide only one book per person. However, if you already have one or more of my books, I will be happy to sign them as well.
I hope to see you there.
