     Answers Explanation & Hints: The ls -l command provides a “long list” format with more information that includes the following: File type: The hyphen (-) represents a regular file, the d represents a directory. File permissions: The first three letters represent the permissions of the file owner over the file, the next three letters represent the permissions of the group over the file, and the last three letters represent the permissions of others over the fie. The permission letters are as follows: r- read or copy the file w- write to the file x- execute the file hyphen (-) – no value assigned Number of hard links to the file: 1 in this case File owner, self in this case File group: test in this case File size. 15 bytes in this case
