Explanation: 

Detailed explanation-1: -The ls command is a widely used Linux command. In its simplest form, the command lists files and folders within a directory. However, ls doesn’t list hidden files by default. To show hidden files you must use the-a option, which commands ls to list “all” files and folders (including hidden ones).
