WALL(1)                       Linux User's Manual                      WALL(1)



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

SYNOPSIS
       wall [ 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.

NOTES
       There  is  an  undocumented  (well  not  anymore..)  option, "-n", that
       supresses the banner printed by wall .  This is  for  usage  by  rwalld
       (8).   Wall  will  not  allow you to use that flag if wall is installed
       set-group-id and the user executing wall is not root.

       For every invocation of wall a notification will be written to  syslog,
       with facility LOG_USER and level LOG_INFO.

ENVIRONMENT
       Wall  ignores the TZ variable - the time printed in the banner is based
       on the systems local time.

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