Disable screen outputting “[screen is terminating]”

Question

How do I disable the output when you are done with a screen from the screen command?

Example:

function foo()
{
    echo "Testing..."
    sleep 2
    echo "Done!"
}
export -f foo
screen -q bash -c "foo" &> /dev/null

It all works as expected, however I cannot find out how to disable the "[screen is terminating]".

Answer 1

There are only two solutions that I can think of. The first is to modify the screen code itself and recompile. The second is to have something like an expect wrapper around the program (untested):

#!/usr/bin/expect -f
spawn screen -q bash -c foo
interact {
    "\[screen is terminating]" exit
}
