The command "wall ${message}" is used to display a message to all logged-in users on a Unix-like operating system.
Here's an explanation of the different parts of the command:
-
"wall" is a command that stands for "write all" and is used to send a message to all users.
-
"${message}" is a placeholder that represents the actual message you want to send. You can replace it with the desired text or variable containing the message you want to display.
When this command is executed, the specified message will be broadcasted to all users who are currently logged in to the system. The message will appear on their terminal or command line interface, notifying them of the content you want to convey.
