Collections Sysadmin & DevOps Collection CompTIA Linux+ CompTIA Linux+ 2014 Powered By LPI: LX0-104
The shell, and shell scripting, provides an incredible interface to running, automating, and maintaining a Linux system. The ability to manipulate the shell is a very powerful tool for any administrator of a Linux system. In this course, you will learn how to use and configure the shell environment, create shell scripts for automating tasks, manage users and groups, use Cron, AT, and Anacron to automate tasks, and learn how to configure the localization and timezone properties of a Linux system. This course is one of a series in the learning path that covers the objectives for the CompTIA Linux+ exams LX0-104.
