Sending files to a specific user
In order to send files to a specific user, the sending and receiving systems must be running either Basic Networking Utilities (BNU) or some version of the UNIX-to-UNIX Copy Program (UUCP).
Use the uuto command to send file from one system to another. It is part of the uucp command and simplifies the file exchange process for senders and receivers. The uuto command sends files to a specific user and deposits them directly into the user's personal directory under that system's BNU public directory. It notifies the recipient that a file has arrived. The recipient uses the uupick command to handle the new file.
