Unable to make batch file prompt for input when invoked through puppet exec

I have a simple batch script which should prompt users for 2 inputs. The batch file works fine on it's own but when I invoke it through puppet exec, the execution does not wait for user input. It simply passes it.

Batch file is invoked as below

file { 'C:/mydir/myfile.bat':
ensure => 'file',
source_permissions => 'ignore',
source => 'puppet:///modules/mymodule/myfile.bat',
 exec { 'execbatch':
 command => "C:/mydir/myfile.bat",

Do I have to pass any additional parameters for the batch file to become interactive?

Puppet is not designed to run interactivly and therefore puppet takes care that your script will not block for user input. Technically puppet redirects STDIN (which is your terminal/keyboard by default) to read from from the pseudo file NUL (or /dev/null on linux)

So to answer your question

Do I have to pass any additional parameters for the batch file to become interactive?

no, because it is simply not possible.

A script that you specify in an exec resource should be a tool to migrate to a specific desired state (which puppet should be able to verify), so if you could explain a bit more what you are trying to accomplish, then we might find a better way to do it (like an answer file or something if it is an installation script)

Thank you for your answer. I'm trying to install a software package on systems automatically but the installation requires few user inputs. For now I have made it work by getting all the required variables through a batch script and passing it on to site.pp.
