My guess is that the shell prompt is "hanging".
Why?

Because you end the last part of the input with backslash.
Which of course causes shell to wait for yet an other line.

And if you don't type that line (or an additional return)
that shell prompt will wait for a very long time.

If that guess should turn out to be true, I suggest you
sleep more, drink more water or tea or coffee or whatever helps,

Or first learn about shell and do some *nix systems 101 in general
before trying to do cluster stuff.
