Which command will list all of the extended attributes on the file afile.txt with the values?

• A. getfattr --all afile.txt
• B. getfattr afile.txt
• C. getfattr --list afile.txt
• D. getfattr --dump afile.txt

Answer: (D)

The command that successfully lists all of the extended attributes on the file `afile.txt`, along with their values, is indeed the one that uses the `--dump` option. This option retrieves all the extended attributes associated with a file and presents both the names of the attributes and their corresponding values in a user-friendly format. Extended attributes are additional metadata that can be attached to files in a filesystem, providing a way to include information beyond the standard attributes like owner, group, or permissions. The `--dump` option specifically indicates that you want to see a full listing that includes these values, making it useful for users who need to assess or report on the attributes associated with their files. In contrast, other commands mentioned do not provide the same level of detail. For instance, some would return only the names of the attributes without the values or might omit entries based on specific criteria, which would not meet the requirement of listing both the attributes and their values comprehensively.
