The mesg 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:
If no arguments are given, mesg displays
the present message status to the standard output.
The mesg utility exits with one of the
following values:
0 1>1Disallow messages from other users to the current terminal:
mesg nAllow messages from other users to ttyp1 (assuming you are also logged in on that terminal):
mesg y </dev/ttyp1Previous versions of the mesg 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.
The mesg utility conforms to
IEEE Std 1003.1-2001 (“POSIX.1”).
