WALL(1) FreeBSD General Commands Manual WALL(1)
NAME
wall -- write a message to users
SYNOPSIS
wall [-g group] [file]
DESCRIPTION
The wall utility displays the contents of file or, by default, its stan-
dard input, on the terminals of all currently logged in users.
Only the super-user can write on the terminals of users who have chosen
to deny messages or are using a program which automatically denies mes-
sages.
-g Send messages to users in this group. This option may be speci-
fied multiple times, and any user in any of the specified groups
will receive the message.
SEE ALSO
mesg(1), talk(1), write(1), shutdown(8)
HISTORY
A wall command appeared in PWB UNIX.
BUGS
The sender's LC_CTYPE setting is used to determine which characters are
safe to write to a terminal, not the receiver's (which wall has no way of
knowing).
The wall utility does not recognize multibyte characters.
