DESCRIPTION

14       Wall  sends a message to everybody logged in with their mesg(1) permis‐
15       sion set to yes.  The message can be given as an argument to  wall,  or
16       it can be sent to wall's standard input.  When using the standard input
17       from a terminal, the message should be  terminated  with  the  EOF  key
18       (usually Control-D).
19
20       The length of the message is limited to 20 lines.  For every invocation
21       of wall a  notification  will  be  written  to  syslog,  with  facility
22       LOG_USER and level LOG_INFO.

OPTIONS

26       -n     Suppresses  the  normal  banner  printed by wall, changing it to
27              "Remote broadcast message".  This option is only  available  for
28              root   if  wall  is  installed  set-group-id,  and  is  used  by
29              rpc.walld(8).
30

ENVIRONMENT

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