Имя (Name)

mesg - display (or do not display) messages from other users

Синопсис (Synopsis)

mesg [option] [n|y]

Описание (Description)

The mesg utility is invoked by a user to control write access
       others have to the terminal device associated with standard error
       output. 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.


Аргументы (Arguments)

n
