Linux shell scripts can be used to automate and schedule repetitive tasks. The proper management of scripts involves an understanding of how to work with script components such as variables, parameters, functions, redirection, as well as conditional and looping constructs. In this course, we'll begin with an overview of Linux shell scripting, including covering common commands used in scripting such as tee, awk, sed, grep and egrep. We will then discuss script comparison operators, how to pipe command output to other commands and how to use input and output redirection. Next, we'll cover how to use various conditional statements such as "if", and how to use various looping constructs such as "for" and "while". Then, we'll cover how to manage Linux environment and shell script variables followed by working with array variables. Lastly, we'll create and run Linux shell scripts followed by scheduling and troubleshooting scripts. This course can be used to prepare to the Linux+ XK0-005 certification exam.

CompTIA Linux+: Application Containers
Application containers are commonly used by both server admins and software developers. Linux technicians must possess skills related to the installation and management of container hosts and Kubernetes clusters. In this course, we will explore the benefits of application containers and find out how they differ from virtual machines. Then we will learn how to install Docker on Linux, discover the Docker container hosting platform, and list common Docker CLI commands. Next, we will create a container overlay network and manage containerized applications, create a container registry, and create a container image from a dockerfile.
