NAME
       wall -- send a message to everybody's terminal.


SYNOPSIS
       wall [-n] [ message ]


DESCRIPTION
       Wall sends a message to everybody logged in with their mesg(1) permis-
       sion set to yes.	 The message can be given as an argument to wall,  or
       it  can	be  sent  to  wall's standard input.  When using the standard
       input from a terminal, the message should be terminated with  the  EOF
       key (usually Control-D).

       The  length  of the message is limited to 20 lines.  For every invoca-
       tion of wall a notification will be written to syslog,  with  facility
       LOG_USER and level LOG_INFO.


OPTIONS
       -n     Suppresses  the  normal  banner printed by wall, changing it to
	      "Remote broadcast message".  This option is only available  for
	      root  if	wall  is  installed  set-group-id,  and	 is  used  by
	      rpc.walld(8).



ENVIRONMENT
       Wall ignores the TZ variable - the time printed in the banner is based
       on the systems local time.


SEE ALSO
       mesg(1), rpc.rwalld(8).
