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 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).
