mesg(1)                             CLIX                             mesg(1)



  NAME

    mesg - Permits or denies messages to a terminal

  SYNOPSIS

    mesg [-n] [-y]

  FLAGS

    -n   Blocks messages to the user's terminal.

    -y   Allows messages to the user's terminal.

  DESCRIPTION

    The mesg command, when given the -n flag, forbids messages from write by
    revoking nonuser write permission on the user's terminal.  The mesg
    command, when used with the -y flag, reinstates permission.  When mesg is
    used without flags, it reports the current state without changing it.

  EXAMPLES

    1.  To disallow messages to your terminal, enter the following:

        mesg -n


    2.  To allow messages to your terminal, use the following:

        mesg -y


  FILES

    /dev/tty*

  SECURITY CONSIDERATIONS

    If your system is running CLIX-TS, this command will operate differently.
    Refer to the CLIX-TS Secure Facilities User's Guide for more information.

  EXIT VALUES

    The exit status is 0 if messages are receivable, 1 if not, 2 on error.
