What is the purpose of the command 'ls' in Linux?

The command 'ls' in Linux is primarily used to list the files and directories present in the current working directory. When executed, it provides a visual representation of all the contents, allowing users to see what files or directories are available. It can also be combined with various options that modify its output, such as displaying hidden files or providing detailed information about file attributes.

The functionality of 'ls' makes it an essential tool for navigation and file management within a Linux system, as it provides essential information needed to perform further actions, such as opening files, copying, or deleting them. The versatility of this command in listing contents makes it a fundamental practice for anyone working in a Linux environment.
