What does the --help option do?

The --help option in Linux commands provides a quick overview of the command's usage, including available options and syntax. When you append --help to a command, it typically displays a summary of how to use that command, along with descriptions of its options.

Example:

For instance, if you run:

ls --help

You will see information about the ls command, including:

• Basic usage
• Available options (like -l for long format, -a for all files, etc.)
• Examples of how to use the command

This is a useful way to get help without needing to look up documentation or man pages. If you have any more questions or need further clarification, feel free to ask!
