Send messages to all users on Linux
- To send a message to your users in intergrated manner, use the Wall command as follows:
wall "System will go down for 1 hours maintenance at 6:00 PM"
You can write your message simply after the word Wall and between quotes and press Enter and after inter this message will be sent to users quickly.
- Now if you intend that after receiving the message by the users, the system will not display the command line until it hits Inter to make sure that the user has read the message, you must use the n parameter.
wall -n "System will go down for 1 hours maintenance at 6:00 PM"
This way you can share notifications about your server with other online users to be notified of the server status.We hope you have taken full advantage of the technique of sending messages to all users on Linux by the Wall command.
If you have any questions or problems, you can ask the Ask system to provide guidance.
