reg-copy:tldr:0985c

This is a command used in the Windows Command Prompt or PowerShell to copy a registry key from one location to another. Here's how to break it down:

• reg: This is the command to interact with the Windows Registry.
• copy: This is the action to copy one registry key to another location.
• ${old_key_name}: This is the source registry key that you want to copy. The ${} syntax is used to represent a variable, so this part should be replaced with the actual name of the old key in the command.
• ${new_key_name}: This is the destination where you want to copy the registry key. Again, this should be replaced with the actual name of the new key in the command.
• /f: This is an optional parameter that forces the copy operation without asking for confirmation.

In summary, this command will copy the registry key specified by ${old_key_name} to the location specified by ${new_key_name}. The /f flag ensures that the copy is done without the need for user confirmation.
