# Introduction In Linux systems, file permissions are crucial for controlling access to files and directories. This challenge will test your ability to manipulate file permissions using the `chmod` command, which is an essential skill for system administrators and Linux users. ## Environment LabEx uses Red Hat Universal Base Image 9 (UBI9) to simulate the exam environment. It may not be identical to the actual RHCSA exam environment, but it provides a good representation of the tasks you'll encounter. There are two users in the environment: - `labex`: A standard user with sudo privileges, password: `labex`. - `root`: The system administrator, password: `redhat`. The challenge features real exam questions, along with explanations, requirements, and automated verification scripts to help you confirm task completion. It effectively simulates the knowledge areas covered in the RHCSA exam.
