Editor to share with you how to use the write command of the Linux system. I hope you will get something after reading this article. Let's discuss it together.

Sometimes there are multiple users working on a server, so some necessary communication is particularly important. For example, when I have to shut down a service, or need to restart the server, of course, I need to notify the user who logs in to the server at the same time, I can use the write command.

Syntax write user [ttyname] parameter description:

User: the user account that prepares to send messages

Ttyname: if users have more than two tty connections at the same time, they can choose the appropriate tty to send messages.

Instance sends a message to Rollaend, and Rollaend has only one connection

Write Rollaend, the next step is to type the message. Press ctrl+c when finished.

The connection that sends the message to Rollaend,Rollaend is pts/2,pts/3.

Write Rollaend pts/2, the next step is to type the message. Press ctrl+c when finished.

Note: if the other party sets mesg n, the information box will not be transmitted to the other party at this time.
