 SYNTAX

       /etc/wall

 FUNCTION

       wall writes a message to all users

       that are currently logged on.

       wall reads its standard input until

       end-of-file, then it sends your message

       preceded by ...

         Broadcast Message from ... 

       to all logged in users not protected by mesg command.

 NOTE: wall almost invariably is used

       by the system administrator prior to 

       shutting down the system!
