WALL(1)			      Linux User's Manual		       WALL(1)

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

SYNOPSIS
       wall [ message ]

DESCRIPTION
       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 20 lines.

NOTES
       There  is  an  undocumented (well not anymore..)	option,	"-n", that su-
       presses the banner printed by wall .  This is for usage by rwalld  (8).
       Wall  will  not	allow  you  to use that	flag if	wall is	installed set-
       group-id	and the	user executing wall is not root.

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

ENVIRONMENT
       Wall  ignores the TZ variable - the time	printed	in the banner is based
       on the systems local time.

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