Review on e-TechServices.com, Inc. by Hikeboy Ramey

This is an excellent resource of information regarding Unix/Linux system administration for those who are new to this technology or have limited experience with it.

The site has many features that can be accessed without logging into an account with them including videos tutorials etc., which makes things accessible even when not logged onto their website! There could definitely always more content available but I would recommend trying out some of these resources as they're pretty good if you haven't already done so. Since we utilize Linux systems internally at our work place all day long every single week, there was never really anything else needed aside from maybe having access to certain documentation online while working away from home (which isn’t too uncommon). We were utilizing CentOS / RedHat Enterprise 7 along w/ Oracle Database 10gR2 & 11G R1 databases via MSSQL server 2008r2 database applications within a Windows environment.
