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) permission 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  broad-
              cast  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  sys-
       tems local time.


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