UNIX write message to users on server

You can message users currently logged on to a UNIX server.

First, check who’s logged on. Enter the ‘who’ command as below:

#>who
user1 pts/0 05 Apr 09:30 (10.170.1.50)

Here you find that the user ‘user1′ using ‘pts/0′ has logged on.

To message this user:

#>write user1 pts/0

And the user would see something like below, to which they can reply in the same manner.

Message from root on server1 (pts/1) [Fri 5 Apr 10:28:19 2013] ...
hi


You can end this session by entering:

Ctrl+D
