Try a Sample Question

CompTIA Linux+ — Sample · easy

Which command lists the contents of a directory including hidden files and detailed attributes such as permissions and ownership?

A ls -la

B ls -a

C ls -d

D ls -R

Explanation. The -l flag produces a long listing with permissions and ownership, and -a includes hidden dotfiles, so 'ls -la' shows both. 'ls -a' alone omits the long format, '-d' lists directory entries themselves, and '-R' recurses without long detail.
