What if home.html doesn't exist?

If home.html does not exist when you run the command:

mv -i test.txt home.html

The command will simply rename test.txt to home.html. Since there is no existing file with that name, there will be no prompt, and the operation will complete successfully.

In summary, if home.html doesn't exist, it will be created as a result of the command. If you have more questions or need further clarification, feel free to ask!
