[-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

and level
LOG_INFO.


 

OPTIONS

Suppresses the normal banner printed by
wall,

changing it to "Remote broadcast message".
This option is only available for root if

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.
