In a shell I call:
/usr/bin/curl https://api.stripe.com/v1/tokens -u 23473248756384765 -d "card[number]=4242424242424242" -d "card[exp_month]=12" -d "card[exp_year]=2015" -d "card[cvc]=123"
The remote host requires me to enter a password at that point by returning:
Enter host password for user:
All i need to do is send a CR because the password has already been established.
How can I use the shell to send a second line?
