- Synopsis:
- mesg [yes|no]
-
- Description:
- This command works exactly like the Unix command of the same name. It
- effectively removes the world-write permissions on the client's tty,
- such that incoming talk requests and writes are blocked. It is most
- useful for dodging "flash" bombs; talk requests with special escape
- sequences in the username that scramble vt100 terminals.
-
- MESG used with no arguments displays the current setting.
-
- Other Notes:
- This command has the undesired side effect of blocking legitimate talk
- requests. Talk and write are not blocked, however, when sent from the
- host's superuser.
