Control Access to Files
File permissions determine who can read, write, or execute a file. We will learn how to control access by changing the file permissions and owner/group.
Overview
Managing file permissions is a fundamental skill for any Red Hat Enterprise Linux (RHEL) system administrator. In this hands-on lab, you’ll learn how to control access to files by understanding and modifying file permissions, ownership, and groups using the Command Line Interface (CLI). Mastering these tasks is essential for daily operations and plays a critical role in preparing for the Red Hat Certified System Administrator (RHCSA) certification.
