CompTIA Linux+ XK0-006 (V8) Practice Question

The -s (long form --skip-base) option instructs getfacl to skip files that only possess base ACL entries. These are the standard entries for user, group, and other that correspond to the traditional file mode bits. The -R (long form --recursive) option makes the command process all files and directories under the specified path. Therefore, getfacl -R --skip-base /projects correctly produces a report showing only the filesystem objects with extended ACLs.

The other options are incorrect:

• Using --omit-header (-c) only suppresses the three-line comment header from the output; it does not filter the files that are displayed.
• The -d flag shows the default ACL for a directory, but it does not filter the output to show only objects with extended ACLs.
• The --numeric (-n) flag converts user and group names to their numeric IDs in the output but does not change which files are reported.
