Linux consists of many tools to manipulate files, streams, and processes from the command line that an administrator really needs to know in order to get the most from their system. This course will describe and show the basic usage of some of the Linux tools that can be used to manipulate files, stream data, and manage processes. You will also learn how to prioritize processes and how to use basic Regular Expressions to do advanced searches and matches against files and file contents. This course is one of a series in the Skillsoft learning path that covers the objectives for the CompTIA Linux+ exams LX0-103.

Target Audience
Administrators or advanced Linux users who need to manipulate files, file contents, or processes from a command line shell
