The phrase “SCP R” is ambiguous, but the most likely meaning is SCP as in the Secure Copy command. In that case, the basic code is scp, used to copy files securely between machines.

Common usage

  • Copy a file to a remote server: scp file.txt user@host:/path/
  • Copy a file from a remote server: scp user@host:/path/file.txt .
  • Copy a folder: scp -r folder/ user@host:/path/

Important note

If you meant SCP in another context, such as the California Safer Consumer Products regulations, then “code” would refer to the regulation text in Title 22, Division 4.5, Chapter 55.
