NAME
     wall — write a message to users

SYNOPSIS
     wall [-n] [file]

DESCRIPTION
     Wall displays the contents of file or, by default, its standard input, on
     the terminals of all currently logged in users.

     sages.

     Reading from a file is refused when the invoker is not superuser and the
     program is suid or sgid.
