The command "reg ${command} /?" is used to display the help documentation for a Windows Registry command.

Here's a breakdown of each component:

• "reg" refers to the command-line tool in Windows used to interact with the system registry.
• "${command}" is a placeholder representing a specific command or operation you intend to execute using the "reg" command. It can be replaced with an actual command, such as "query" or "export". For example, if you want to view the help documentation for the "query" command, you would use "reg query /?".
• "/?" is an argument that is appended to most command-line tools in Windows to display detailed information about the command or operation. When using "/?" with the "reg" command, it will show the available options, syntax, and examples related to the specified "${command}".

Combined, "reg ${command} /?" allows you to view the help information for a specific registry command, providing instructions and explanations on how to use it properly.
