To answer the question in post #1.
It is not possible for a background task to type input on the foreground keyboard.
It is not normal to create a background process which outputs to a terminal - it will clash with any foreground process.

hmm... the script should look for running foreground processes on same terminal to prevent this? Smilie
there's just one problem left - guess we can not check if some chars already entered into prompt?

I think you've missed the point about background processes.

maybe you are right - background processes should not output something to stdout/terminal.
I just thought about emergency situation of processes in the back..
how to inform the terminal user?

how does command 'shutdown +15' handle this?

The shutdown command is machine-specific. They usually use thewall command.
Code:
man wall
man write

The messages from wall or write still mess up the display on the receiving terminals.

We use email for alerts and also have dedicated monitor terminals for events (some of which may be alerts).
