I have been playing with linux for a few years now, a lot of it has been working with tutorials on line that walked me step by step through the process of getting things set up. I have set up an Email server, a few webservers. PBX, Samba servers and a few other odds and ends and I have been using Raspberry pi's for almost 4 years now. I am okay at the command line, but far from a pro. I can do a lot of the basics like setting up users, changing file rights, installing packages... I am an IT administrator and deal about 20% in Linux right now. A linux sysadmin position is opening up soon, and the plan is to work my self into that position in the next 7 months. I have the LPIC-1 training guide(The new version 5 that just came out) but I started thinking, I know I'm not an absolute beginner, but I bet the Linux Essentials Certification train could at least confirm, and I'm sure there will be items that I haven't touched before. So, my question is, it worth starting with the essentials training? If so. what book to use. The LPIC certification guide for the new Version1.6 wont be released until January, and I need to be studying right now. the version 1 book that is available right now is from 2015. I now I would pick up useful info from it, but is there a better option? Thanks in advance for the advice, and I look forward to skimming through the forum.
