I want to run a command which results in the user being prompted several times for some input.
It would be easy to create a text file with the inputs and then run the command like:

@output = `cmd < textfile`;

My problem - I want to retrieve and process the output after each input and not just at the end.

I thought that the best way to do this would be to open a filehandle like this:

open (P1, "|cmd");
print P1 'input1';
# process output
print P1 'input2';
# process output
print P1 'input3';
close P1;
# process final output

However, I cannot get this to work successfully.
Am I on the right track or is there a better way?
Any help greatly appreciated
