If write access +is allowed, then programs such as +.BR talk (1) +and +.BR write (1) +may display messages on the terminal. +.PP +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, +.B mesg +should be executed in your login scripts. +.PP +Options available: +.TP +.B n +Disallows messages. +.TP +.B y +Permits messages to be displayed. +.PP +If no arguments are given, +.B mesg +displays the present message status to the standard error output. +.PP +The +.B mesg +utility exits with one of the following values: +.TP +.I "\ 0" +Messages are allowed. +.TP +.I "\ 1" +Messages are not allowed. +.TP +.I "\>1" +An error has occurred. +.SH FILES +.I /dev/[pt]ty[pq]? +.SH "SEE ALSO" +.BR biff (1), +.BR talk (1), +.BR write (1), +.BR wall (1), +.BR login (1), +.BR xterm (1) +.SH HISTORY +A +.B mesg +command appeared in Version 6 AT&T UNIX. + +.SH AVAILABILITY +The mesg command is part of the util-linux package and is available from +ftp://ftp.kernel.org/pub/linux/utils/util-linux/. -- cgit v1.2.3-55-g7522
