What does the command 'ls' do?

The command 'ls' is used to list files and directories within the current working directory or a specified directory. When you run 'ls' in a terminal, it displays the names of files and directories, helping users navigate and stay organized within the filesystem. This command can include various options to modify its output, such as showing hidden files, detailed information about each file's attributes, and sorting files by different criteria.

The primary function of 'ls' is thus to provide a view of the contents of a directory, making it a fundamental command for anyone working with a Linux system. Understanding how to use 'ls' effectively is essential for managing files and directories efficiently in a Linux environment.
