talk
is a Unix text chat program, originally allowing messaging only between the users logged on to one multi-user computer—but later extended to allow chat to users on other systems.
Although largely superseded by IRC and other modern systems, it is still included with most Unix-like systems today, including Linux,[1] BSD systems[2] and macOS.[3]
