I would like to know how to execute a command inside a screen session. i searched and I found this :

screen -S nameofscreen -X stuff "command"

When I type this, the command is typed inside the screen but it is not executed. So my queston is how to press enter using this command.

I'd do something like this:

screen -S sessionName bash -c 'cmd; exec bash'

it starts a new session executes cmd and launches shell (otherwise it'd drop that new session).

-X will allow you to send input to a specified session -- that's why your command didn't execute. To execute it you'd need to add enter sign like Paul suggested. It can be done with Ctrl+v and then Enter. That will produce that ^M. So:

screen -S sessionName -X stuff 'cmd^M'

That, in itself, won't however attach a detached session.
