Overview
In Linux, permissions control who can access and modify files and directories. Understanding permissions is essential for maintaining security and proper file management. Each file and directory has three types of permissions: read, write, and execute. These permissions can be assigned to three different user categories: the owner, the group, and others. Learning how to manage these permissions helps you protect your data and collaborate effectively.
