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.

SEE ALSO
     mesg(1), talk(1), write(1), shutdown(8)

HISTORY
     A wall command appeared in Version 7 AT&T UNIX.  Support for -g was added
     in NetBSD 2.0 (from OpenBSD 2.0).
