Write (Unix)
From Wikipedia, the free encyclopedia
- The correct title of this article is write (Unix). The initial letter is shown capitalized due to technical restrictions.
write can refer to several Unix commands. All known variations of write are used to write messages to another user. The most popular variation sends a message directly to another user's TTY

[edit] Usage
The correct syntax for the write command is:
write user [tty] message
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.
[edit] Example
A conversation initiated between two users on the same machine:
11:19 AM# write root pts/7 test
Will show up to the user on that console as
Message from root@punch on pts/8 at 11:19 ... test
[edit] History
A version of the write command appeared in the First Edition of the Research Unix operating system. Another variation of write writes a message to a user on a Windows network, using the SMB packet format.
