Running a shell command from Ruby: capturing the output while displaying the output?

Question

I have a problem.

I want to run a ruby script from another ruby script and capture it\'s output information while letting it output to the screen too.

Answer 1

Have your script do its prompt output to stderr.

echo "Enter something" >&2
read answer
echo "output that will be captured"

This will be done for you if you use read -p to issue the prompt:

read -p "Enter something" answer
echo "output that will be captured"
