Screen troubles?

Question

linux

Hello linux gurus.
I ask you about: There is a running screen (Screen), on one socket. There are 3 tabs inside the session.
0 - daemon
1 - daemon
2 - daemon 3
- empty Something like screen -p number_tabs - but something doesn't work. CHADNT? Thank you!

Answer 1

screen -S mysession -p 1 -X stuff 'ls -l'`` echo -ne '\
015'`

Answer 2

tmux send -t 'foo.3 echo "bar" ENTER'; attach;
I could make a mistake in parentheses or escaping, you can take the last session, something should be worse in the screen.
