Secure file copy allows you to copy files between two hosts in a secured way. Below I posted some basic usage of this useful command.
From local to remote
scp source_file [email protected]:/directory/target_file
scp db_dump.tar.gz [email protected]:/backups/db_dump.tar.gz
From remote to local
scp [email protected]:/directory/source_file target_file
scp [email protected]:/backups/db_dump.tar.gz db_dump.tar.gz
Keep in mind that the above syntax of Scp command, works perfectly on OS X.
