Fundamentals of Linux

Course details

CentOS is a community-based enterprise class operating system focused on delivering a robust open source ecosystem. IT offers a consistent manageable platform that suits a wide variety of deployments. For open source communities, it offers a solid, predictable base to build upon, along with extensive resources to build, test, release, and maintain their code. Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. In this course you will work through all the basic Linux and command-line concepts. You will start with how to install Linux and then learn the concepts of virtualization, how to work with VirtualBox, install CentOS 7 in VirtualBox, and connect to your VM through SSH. Then you will learn about the command-line, how to work efficiently with the shell, navigating the Linux filesystem, and creating and deleting dot files and dot directories. Then you will learn about creating user permissions and group permissions and viewing and editing files. Then you will learn what every sysadmin needs to know about the command-line, master additional programs bash shell scripts, and learn how to automate scripts. Finally you will explore more advanced command-line concepts, troubleshooting, and understanding ACL.

This course explains and teaches all the important command-line tools and utilities, using very easy to understand, real-world examples to follow along with—in short, you'll learn everything you really need to know about Linux when starting out from scratch as a new system administrator or for any other reason.
