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).
