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

       wall [-n] [ message ]

       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  notifi-
       cation will be written to syslog, with facility LOG_USER and level LOG_INFO.

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

       Wall  ignores  the  TZ  variable - the time printed in the banner is based on the system's
       local time.

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