NAME
mesg - permit or deny messages
SYNOPSIS
mesg
[
n
] [
y
]
[answerback message]
DESCRIPTION
Mesg
with argument
n
forbids messages via
write
and
talk(1)
by revoking non-user
write permission on the user's terminal.
Mesg
with argument
y
reinstates permission.
All by itself,
mesg
reports the current state and answerback message without changing it.
The answerback message
is used as an automatic response to anyone who tries to send you a msg.
The existing answerback message is removed on subsequent
mesg
command invocations (except when no arguments are given).
EXAMPLE
mesg n Please send me mail instead.
BUGS
mesg
will not work within a
script(1)
session because there is no way for it to find out what terminal
you are really signed on to.
FILES
/dev/tty*
/usr/tmp/mesg.tty*
SEE ALSO
write(1), talk(1)
DIAGNOSTICS
Exit status is 0 if messages are receivable,
1 if not, 2 on error.
NOTE
Answerback messages are a Waterloo addition.
