NAME
mesg
- display (do not display) messages from other users
SYNOPSIS
[n | y
]
DESCRIPTION
The
utility is invoked by a user to control write access others
have to a terminal device.
Write access is allowed by default, and programs such as
talk(1)
and
write(1)
may display messages on the terminal.
The first terminal device in the sequence of devices associated with standard
input, standard output and standard error is affected.
The following options are available:
n
Disallow messages.
y
Permit messages to be displayed.
If no arguments are given,
displays the present message status to the standard output.
EXIT STATUS
The
utility exits with one of the following values:
0
Messages are allowed.
1
Messages are not allowed.
>1
An error has occurred.
EXAMPLES
Disallow messages from other users to the current terminal:
"mesg n"
Allow messages from other users to
ttyp1
(assuming you are also logged in on that terminal):
"mesg y </dev/ttyp1"
COMPATIBILITY
Previous versions of the
utility wrote the message status to the standard error output and
affected the terminal attached to standard error without first trying the
standard input or output devices.
