Linux for sysadmins | Linux from the command line -- Advanced drive usage and partitioning with LVM
This article gives you the basics for using the powerful LVM tool in conjunction with multiple Linux file-systems. This is the basic command line method for the two basic Linux types, RH and Debian, and it's a good way for you to grasp the concepts. However keep in mind that most systems have other, preferred tools to perform these operations so RTFM for your Distro. OpenSUSE users, for example, should use the "Partitioner" module of the YaST2 administration tool to perform these functions.

Linux from the command line -- Pulling info out of proc with procinfo
Linux from the command line -- Pulling info out of proc with procinfo
Most of the system information you could ever want from your Linux system is ready and waiting for you in the proc folder. Remember, everything is a file in Linux (or at least it was until it was infected with systemd) so you can use simple tools like ls and cat to find and display this info in any way you wish. Throw in grep, sed, awk, and watch and you can create some pretty impressive output of your system's innards. However, for a quick and simple way to get the most commonly used data out, procinfo has you covered.

Linux for sysadmins | Linux from the command line -- Monitoring servers with Glances
Being a good sysadmin requires a lot of things, two of which are monitoring in order to spot trends which may indicate impending issues so you can head them off before they do, and diagnosis skills to find problems quickly when they do happen. Good monitoring tools and skills are a major part of achieving those two things.
Luckily Linux has a huge portfolio of monitoring tools available for every kind of task and resource. Glances is one of them.
