Managing File Permissions on Remote Host

Through this lab, you will learn how to manage file and directory permissions on remote hosts using Ansible. Create and manipulate files and directories, check their status, and modify their permissions to understand the power of automation in system administration. By the end of this lab, you'll have a hands-on understanding of how to efficiently control access to files across multiple systems, enhancing both security and productivity.
