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. + +The *mesg* utility silently exits with error status 2 if not executed on terminal. In this case execute *mesg* is pointless. The command line option *--verbose* forces mesg to print a warning in this situation. This behaviour has been introduced in version 2.33. + +== 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. + +include::man-common/help-version.adoc[] + +== 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]?_ + +== HISTORY + +A *mesg* command appeared in Version 6 AT&T UNIX. + +== SEE ALSO + +*login*(1), +*talk*(1), +*write*(1), +*wall*(1), +*xterm*(1) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] |
