- Replace the destination file with the one from the source directory:

`replace {{path/to/file_or_directory}} {{path/to/destination}}`

- Add files to the destination directory instead of replacing existing files:

`replace {{path/to/file_or_directory}} {{path/to/destination}} /a`

- Interactively copy multiple files, with a prompt before replacing or adding a destination file:

`replace {{path/to/file_or_directory}} {{path/to/destination}} /p`

- Replace even read only files:

`replace {{path/to/file_or_directory}} {{path/to/destination}} /r`

- Wait for you to insert a disk before it replaces files (originally to allow inserting a floppy disk):

`replace {{path/to/file_or_directory}} {{path/to/destination}} /w`

- Replace all files in subdirectories of the destination:

`replace {{path/to/file_or_directory}} {{path/to/destination}} /s`

- Replace only files in the destination directory which are older than the files in the source directory:

`replace {{path/to/file_or_directory}} {{path/to/destination}} /u`

- Display detailed usage information:

`replace /?`
