Thanks for reply, your post is very interesting.
But proposed code does not work correctly for me:
i try this in shell:
screen -c /dev/null -S test -D -m bash -i & until screen -c /dev/null
-S test -X echo '' &>/dev/null; do echo .; sleep 0.1; done; screen -c
/dev/null -S test -X stuff 'sleep 10\015'
'sleep 10' command seems to be not executed (not seen in ps axf)
doing further 'screen -r test' gives me unusable shell.
