Sending and receiving files
The commands used for sending and receiving files through a BNU connection include the uucp and the uusend commands.
Use the uucp command and options to exchange files within your local system, between your local and a remote system, and between remote systems. The uucp options can, for example, create directories to hold files on the receiving end or mail messages on the success or failure of file transfers.
Use the uusend command to send files to a remote system that is not directly linked to the sending system but is accessible through a chain of BNU connections. Though equipped with fewer options than the uucp command, uusend is included among the BNU utilities to satisfy the preferences of BSD UNIX-to-UNIX Copy Program (UUCP) users.
