Synopsis

write user [tty]

The write program is more primitive than talk: it sends lines of text from one logged-in user to another on the same Mac. It cannot communicate over a network:

write smith
Hi, how are you?
See you later.
^D

^D ends the connection. write is also useful in pipelines for quick one-off messages:

echo 'Howdy!' | write smith
