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) permisā 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. For every invocation of wall a notification will be written to syslog, with facility LOGUSER and level LOGINFO. 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). AUTHOR Miquel van Smoorenburg, miquels@cistron.nl 15 April 2003 WALL(1)
