The write command was included in the First Edition of the Research Unix operating system.[2] A similar command appeared in Compatible Time-Sharing System.[3]

The syntax for the write command is:
$ write user [tty]

The write session is terminated by sending EOF, which can be done by pressing Ctrl+D. The tty argument is only necessary when a user is logged into more than one terminal.[4]
A conversation initiated between two users on the same machine:
$ write root pts/7

Will show up to the user on that console as:
