bypass Yes/No in Shell Script

Question

There is a shell script it asks yes/no multiple times almost 100 times when I run twice on a server. I'm tired of typing yes every time. Is there any way to Run that script just taking yes as a default option.Assume following is my script! FYI, I can not edit my script. Just I can run it using ./ittp-update.sh

  #!/bin/bash
  echo "Do you need to install the necessary compiling tools?"
  select yn in "Yes" "No"; do
case $yn in
    Yes ) sudo apt-get install tools; break;;
    No ) <Here I want to skip to the next step. I originally left it 
          blank and removed the "done" command (after esac command) 
          to do this, but if I choose yes, it skips to the end 
          (where the next "done" command is and ends the script>
esac

echo "Do you need to eidt your configuration?"
select ny in "No" "Yes"; do
   case $ny in
    No ) <what do I put here to skip to the next tag 
         (labeled compile for example purposes); break;;
    Yes ) 
esac
 echo "You have 3 options with how you can edit you config file."

Answer 1

If you just need to answer "Yes" to everything, you can use

yes Yes | ./ittp-update.sh

How this works:

1. The program yes prints the string you give it (or "y" if you don't give it anything, since this is the default way to give a positive answer in *nix programs) repeatedly on standard output until it receives SIGPIPE.
2. The pipe (|) connects standard output of the preceding command (yes) to the standard input of the following command (./ittp-update.sh).
3. When ./ittp-update.sh finishes, the shell automatically sends SIGPIPE to any commands connected to it by pipes (only yes in this case).
4. Upon receiving SIGPIPE, yes exits.

See man yes for more information.
