As Jose answered  screen -d -r should do the trick  This is a combination of two commands  as taken from the man page   screen -d detaches the already-running screen session  and screen -r reattaches the existing session  By running screen -d -r  you force screen to detach it and then resume the session     If you use the capital -D -RR  I quote the man page because it s too good to pass up      Attach here and now  Whatever that means  just do it            Note  It is always a good idea to check the status of your sessions by means of  screen -list
