WALL(1)			      Linux User's Manual		       WALL(1)



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 invocation
       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 system's local time.


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