wall: Send a message to users that belong to a specific group.
$ wall --group ${group_name} ${message}
try on your machine
The command "wall" is used to send a message to all currently logged-in users on a Unix/Linux system.
In this particular command, "--group" is an option that specifies the group name to which the message should be sent. The variable "${group_name}" needs to be replaced with the actual name of the group.
The variable "${message}" needs to be replaced with the text that you want to send to the group. It could be a simple string or a more complex message.
So, when you run this command with the appropriate group name and the message, the "wall" command will broadcast the message to all users belonging to that specified group.
