A1: POSIX Access Control Lists (ACLs) are a feature in Linux that allow for a more fine-grained permission control over files and directories than the traditional read, write, and execute permissions. They are crucial for environments where multiple users require different levels of access to shared resources. Q2: What is getfacl? A2: The getfacl command is used to retrieve the access control lists of a file or directory. This tool displays permissions, owner, the group information, and the ACLs themselves, making it easier for administrators to understand and manage permissions effectively.
