The basic syntax for the SCP command is provided below:
/path/to/source/file – This is the source file that you intend to copy to the remote host.
[email protected]: – This is the username and IP address of the remote system. Take careful note of the colon that appears after the IP address.

-r – This option recursively copies a directory alongside its contents.
-r – Preserves the access and modification times of the file being copied.
