Which functionality is provided by command-line switches in DOS?

• A. They limit the number of files a command can affect
• B. They enable commands to run in batch mode only
• C. They allow users to specify options to modify command behavior
• D. They prevent commands from running altogether

Answer: (C)

Command-line switches in DOS are parameters added to commands to modify their behavior, allowing users to customize the execution of those commands according to specific needs. This functionality includes things like changing the format of output, specifying different input files, or altering various settings to achieve different results without changing the command itself. For example, when using the "DIR" command, a switch can specify that the files should be listed in a particular order or include hidden files. This flexibility enhances the usability of commands by enabling users to tailor their output and the action taken. The other options do not accurately describe the role of command-line switches. They do not limit the number of files affected by a command, nor do they restrict commands to batch mode or prevent commands from running. Instead, the primary purpose of command-line switches is to provide users the ability to enhance and customize command executions.
