I want to automate the run of the ./configure command. When I normally run it, every time I have to press enter. I want to run this command from a shell script and I don't want it to wait for a user to press enter at each prompt for path. How do I achieve this ? I am using Ubuntu machine with bash shell. Thanks.

mdt-inference@ubuntu:~/MDT/mdst-libreoffice$ ./configure 
Path to Office installation? [/usr/lib/libreoffice] 
Path to Office SDK installation? [/usr/lib/libreoffice/sdk]

Note : I tried the below link but it does not work. How to simulate two consecutive ENTER key presses for a command in a bash script?

I have used "yes" command already but when I run ./configure there are multiple prompts which are more than two. When I use "yes", it just supplies argument to the first prompt only

yes command can be used here (with just 2 enter key) 

yes " " | head -2 | ./configure

In general, this should work. 

yes | ./configure

You might check out the cram Python package:

https://pypi.python.org/pypi/cram

It's designed for straightforward automation of command-line apps, and I've been pleasantly surprised by how well it's worked for my needs so far.
