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 device. The terminal device affected is determined by searching for the first terminal in the sequence of devices associated with standard input, 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.

ENVIRONMENT VARIABLES See environ(5) for descriptions of the following environment variables that affect the execution of mesg: LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS The following exit values are returned: 0 if messages are receivable. 1 if messages are not receivable. 2 on error.
