UUCP

UUCP (Unix-to-Unix Copy Protocol) is a collection of Unix programs that supports file sharing and execution amongst other systems. The primary UUCP commands supported by these programs include the following: uucp - requests the copying of a certain file to a specified system. uux - transmits a UNIX command to another operating system. The command is then queued and waits to be executed. uucico - functions on a UNIX operating system as the application responsible for copying and initiating the execution of commands that have been received. This program typically runs random throughout the day - the copy requests (uucp) and command requests (uux) remain queued until the uucico application is run. uuxqt - executes all commands sent by the uux program. This usually occurs after it has been started by the uucico program. uucico are the applications that actually communicate over the network. They support various protocols depending on what carrier networks are being used.
