How to pass arguments to an interactive script?

I've tried to find a solution to this, but I"m stumped.

OS - RH Linux 5.9

I have a bash script <myProgram.sh> that gets executed manually and creates a small response file. I'm trying to automate the running of this script.

When myProgram.sh runs, it prompts the user to enter 2 pieces of information.

For the first input the user is told to hit Enter for is a line feed.

The second input is [Y]es.

Example:

Code:

./myProgram.sh

First prompt:
Press Enter to Continue

Second prompt:
Enter [Y]es, [N]o) [N]

I'd like to automate the execution of this script.

I figure that if I can do it from the command line, then I can script it.

Here is the closest that I've tried:

echo -e "\n" | ./emocmrsp

This seems to pass in a line feed, which answers the first prompt, but it doesn't pass anything to the second prompt.

So, I"m struggling with what to do for the second prompt.

I tried this but it didn't work.

This echos the linefeed "\n" for the first prompt, but fails for the second prompt.

echo -e "\n" "Y\n" | ./emocmrsp

([Y]es, [N]o) [N]: Invalid value specified.

Any suggestions?

Try

Code:

(echo -e "\n" ; echo -e "Y\n") | ./emocmrsp

Simple echo itself is a newline, so you can use

Code:

(echo ; echo Y)  | ./emocmrsp

$ (echo ; echo Y) | ./emocmrsp
$ (echo -e "\n" ; echo -e "Y\n") | ./emocmrsp

Both commands returned this error:

Does this mean, the second input didn't work?
Is that error or the message from script? What do you expect when you run the script in interactive mode?

Here's the output of the script running in interactive mode. When it asks for an email address, I press enter to get past it. Then I press Y at the last line.

Same error:

Interestingly, these 2 statements returned the same (above) error.

Code:

./emocmrsp <<EOF

Y
EOF

and

Code:

./emocmrsp <<EOF

EOF

It looks like the Y isn't getting read correctly.
