NAME

wall - Sends a message to all users  

SYNTAX

wall [file]


 

DESCRIPTION

The wall command reads from standard input until you press the End-of-File key sequence, or takes its input from the contents of file if you specify it, and sends the input as a message to all users who are logged in. The message is preceded by the heading:

Broadcast Message from [email protected] (tty) at hh:mm

where user is the user invoking wall, node and tty are the node and terminal of that user, and hh:mm is the time of the message.

To override any protections other users have set up, you must be operating with superuser authority. Typically, the root user uses wall to warn all users of an impending system shutdown.

The wall command sends messages to the local node only.
