NAME
mesg - permit or deny messages
SYNOPSIS
mesg [ -n | -y | n | y ]
DESCRIPTION
The mesg utility will control whether other users are
allowed to send messages via write(1), talk(1), or other
utilities to a terminal device. The terminal device affected
is determined by searching for the first terminal in the
sequence of devices associated with standard input, standard
output, and standard error, respectively. With no arguments,
mesg reports the current state without changing it.
Processes with appropriate privileges may be able to send
messages to the terminal independent of the current state.
OPTIONS
The following options are supported:
-n|n Deny permission to other users to send message to the
terminal. See write(1).
-y|y Grant permission to other users to send messages to
the terminal.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment
variables that affect the execution of mesg: LC_CTYPE,
LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 if messages are receivable.
1 if messages are not receivable.
2 on error.
