It seems like you're referring to a command that might be related to copying files, perhaps using a tool called `mega-cp` from the MEGA.nz cloud storage service. However, the specific syntax and usage can vary based on the version and context of the command.
If you're looking to copy files or directories from a local folder to your MEGA.nz account using `mega-cp`, the general syntax would typically look like this:
```bash
mega-cp
