Which option would you use with tar to see a summary of its usage?

• A. tar --help
• B. tar -?
• C. tar -h
• D. tar -usage

Answer: (A)

Using "tar --help" provides a comprehensive display of usage information and options available for the tar command. This option lists all the command-line flags, options, and a brief description of what they do, making it a valuable resource for users seeking to understand how to use tar effectively. The other options do not provide the same level of detail or may not be valid commands. For instance, "tar -?" might not be recognized on some systems as a valid option for getting help, while "tar -h" generally refers to the human-readable format for size. "tar -usage" is not a recognized option and would result in an error. Thus, "tar --help" is the definitive way to obtain a summary of the command's usage directly in the terminal.
