NAME

     wall -- write a message to users


SYNOPSIS

     wall [-g group] [file]


DESCRIPTION

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

     Only the super-user can write on the terminals of users who have chosen
     to deny messages or are using a program which automatically denies mes-
     sages.

     -g      Send messages to users in this group.  This option may be speci-
             fied multiple times, and any user in any of the specified groups
             will receive the message.
