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


wall [-n] [ message ]


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


-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).


Wall ignores the TZ variable - the time printed in the banner is based on the system's local time.


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