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

(8).
