Late yesterday I finished proofing that last of the three books in my Using and Administering Linux: Zero to SysAdmin series.
Although there may be a few more email discussions to clarify various notes I made on the proofs, for me, this project is essentially done. It has taken almost two years from my initial conception of the Linux self-study course that grew into this three-volume set.
As far as I can tell, we are still on track to have all three volumes published before the end of the year.
If you are interested in learning to be a Linux system administrator, this is the self-study course for you. I hope you will check it out. The link above takes you to my page for all three volumes which has links to Apress and Amazon where they can be purchased.
Information is the key to resolving any computer problem, including problems with or relating to Linux and the hardware on which it runs. There are many tools available for most distributions. These tools can be used to obtain huge amounts of information.
