To display the security context associated with files or directories under an SELinux kernel, you can use the ls -Z command.
ls -Z
This will list the files and directories in the current directory, along with their security contexts.
To display the security context for a specific file or directory, use the ls -Z command followed by the name of the file or directory.
For example, to display the security context for the /etc/shadow file:
ls -Z /etc/shadow
The output will display the security context for the file, in the format user:role:type:level.
You can also use the stat command with the --format option to display the security context of a file or directory:
stat --format '%C' FILE_NAME
Replace FILE_NAME with the name of the file or directory that you want to display the security context for.
For example, to display the security context for the /etc/shadow file:
stat --format '%C' /etc/shadow
