uux
uux is a utility that originated with the UUCP (Unix-to-Unix Copy) software suite and is used to execute commands on remote Unix systems through the UUCP network. It fits into the batch-oriented, asynchronous model of UUCP, where users submit requests that are queued, transferred, and run on remote machines rather than being executed in real time on the submitting host.
Operation and role in UUCP: uux processes remote command requests by creating or reading control information
Typical usage: Historically, a user would prepare a control file describing the command to be run on
Historical context and status: uux is part of an older, networked model of Unix systems sharing files
