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).
