Lets you copy a file from one machine to another machine. uucp creates work files and data files, queues the job for transfer, and calls the uucico daemon, which in turn attempts to contact the remote computer. See the uucp (1C) man page for details.
Copies files from the local machine to the public spool directory /var/spool/uucppublic/receive on the remote machine.

See the uuto (1C) man page for details.
