I've been stuck at the that point where I should type echo "Hello" (after the prompt):
I type, as it says, after the prompt: $echo Hello (without the quotes "", because the codecademy's terminal isn't showing, or is not accepting my keybord's commands to the quotation marks " " as I type. I mean, I've been trying to type them, however, they don't appear on the Codecademy terminal).
That bug is happening only in the Commad Line course. I haven't had such a problem with the other courses I've been attending here on Codecademy.
I've tried to type: echo "Hello" (after the prompt), but it shows: echo Hello (which seems to be ok, due to the fact the word Hello apears on the following line of the terminal as if it had been echoed. The problem is the error message that blocks me from moving forward to the next exercise.
