wall

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).
