How do you list all the files in a directory, including hidden files?
The 'ls -a' program is used to list every file in a directory, including hidden files. In Linux, hidden files begin with a dot (.), and 'ls -a' guarantees that they are also visible.
Additionally, candidates should use 'ls -l' to obtain a comprehensive listing that includes ownership, modification dates, and file permissions. This demonstrates their ability to retrieve detailed file information.
