How do you view a directory’s content, including hidden files?

Viewing a directory's content, including hidden files, is commonly achieved using the command ls -a. The -a option stands for "all," and it instructs the ls command to display all files in the directory, including those that are hidden. In Linux, files and directories that begin with a dot (.) are considered hidden and will not be shown in the output of a simple ls command without options.

The other commands or options provided do not accomplish this task. For instance, the ls -l command lists files in a detailed format but does not include hidden files since it lacks the -a option. The command dir -a is generally associated with listing directory contents but is not commonly used in Linux; it's more typical in DOS or Windows environments, and its behavior differs from the ls command. The command view -hidden is not a standard Linux command for listing directory content, making it ineffective for this purpose.

Thus, using ls -a fits the requirement effectively, enabling users to see all files, inclusive of hidden ones.
