screen displays informational messages and other diagnostics in a
message line at the bottom of the screen. If your terminal has a
status line defined in its termcap, screen will use this for displaying
its messages, otherwise the last line of the screen will be temporarily
overwritten and output will be momentarily interrupted. The message
line is automatically removed after a few seconds delay, but it can also
be removed early (on terminals without a status line) by beginning to
The message line facility can be used by an application running in the current window by means of the ANSI Privacy message control sequence. For instance, from within the shell, try something like:
echo "<ESC>^Hello world from window $WINDOW<ESC>\"
where `<ESC>' is ASCII ESC and `^' is a literal caret or up-arrow.
screenwill use this facility to display one line messages. Otherwise these messages are overlayed in reverse video mode at the display line. Note that the hardstatus feature can only be used if the termcap/terminfo capabilities "hs", "ts", "fs" and "ds" are set properly. Default is `on' whenever the "hs" capability is present.
screendelays a new message when another is currently displayed. Defaults to 1 second.
screenis not disturbed by other activity. Defaults to 5 seconds.
