Which command is used to display the security context of files?

The command used to display the security context of files is ls when used with the appropriate options, specifically ls -Z. The -Z option displays the SELinux security context for each file, which provides important information regarding the security policies enforced on the system. This context includes the user, role, type, and level associated with the file, which is critical for managing permissions and security in a SELinux-enabled environment.

While other commands like file, stat, and grep serve different purposes—such as displaying file types, showing detailed information about files, or searching through files for specific patterns—they do not provide the security context that ls -Z does. This makes ls the correct choice for obtaining visibility into file security contexts in environments using SELinux.
