mesg(1) User Commands mesg(1) NAME mesg - permit or deny messages SYNOPSIS mesg [-n | -y | n | y] DESCRIPTION The mesg utility will control whether other users are allowed to send messages via write(1), talk(1), or other utilities to a terminal de- vice. The terminal device affected is determined by searching for the first terminal in the sequence of devices associated with standard in- put, standard output, and standard error, respectively. With no argu- ments, mesg reports the current state without changing it. Processes with appropriate privileges may be able to send messages to the termi- nal independent of the current state.
