This article mainly explains "the usage of write and wall commands under Linux". The explanation in this article is simple and clear, easy to learn and understand. Please follow the ideas of Xiaobian and study and learn "the usage of write and wall commands under Linux" together.

I. Write

Usage: user name; After typing Enter, you and the other party will be in a chat state at the same time, but the person who initiated the connection can only receive the chat content of the person who initiated the chat request, but cannot reply. If you want to reply, you must first initiate a connection to the other party, so that the two people can chat. Note that root can initiate a connection to any person, but others cannot initiate a connection to root. By default, root's message is disabled. If you must initiate a request for root, you must first set the mesg of root to y, so that you can enter,mesg y as root. This will be fine, so that other users can initiate a connection to root.

uptime

Access: All users

Usage: Uptime [-V]

Description: Uptime provides the user with the following information, no additional parameters required:

the present time

The elapsed time since the system was turned on

Number of users connected

System load for the last minute, five minutes and fifteen minutes

Parameter: -V Displays version information.

Example: Uptime

The results are:

10:41am up 5 days, 10 min, 1 users, load average: 0.00, 0.00, 1.99

II. Wall

Usage: After hitting Enter, you can enter what you want to say. After entering what you want to say, press ctrl+D, so that all online users can receive the content of the message at the same time, but this can only be sent once. If you send it again next time, you have to start again. If two online users want to chat all the time, you have to use the write command.
