NAME
mesg - control write access to your terminal SYNOPSIS
mesg [y|n] DESCRIPTION
Mesg controls the access to your terminal by others. It's typically used to allow or disallow other users to write to your terminal (see write(1)). OPTIONS
y Allow write access to your terminal. n Disallow write access to your terminal. If no option is given, mesg prints out the current access state of your terminal. NOTES
Mesg assumes that its standard input is connected to your terminal. That also means that if you are logged in multiple times, you can get/set the mesg status of other sessions by using redirection. For example "mesg n < /dev/pts/46". AUTHOR

NAME
mesg - display (or do not display) messages from other users SYNOPSIS
mesg [option] [n|y] DESCRIPTION
The mesg utility is invoked by a user to control write access others have to the terminal device associated with standard error output. If write access is allowed, then programs such as talk(1) and write(1) may display messages on the terminal. Traditionally, write access is allowed by default. However, as users become more conscious of various security risks, there is a trend to remove write access by default, at least for the primary login shell. To make sure your ttys are set the way you want them to be set, mesg should be executed in your login scripts. ARGUMENTS
n Disallow messages. y Allow messages to be displayed. If no arguments are given, mesg shows the current message status on standard error output. OPTIONS
-v, --verbose Explain what is being done. -V, --version Display version information and exit. -h, --help Display help text and exit. EXIT STATUS
The mesg utility exits with one of the following values: 0 Messages are allowed. 1 Messages are not allowed. >1 An error has occurred. FILES
/dev/[pt]ty[pq]? SEE ALSO

The mesg command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/. util-linux July 2014 MESG(1)
