Need help with the Script to pass stdin in run time

I have put a script inside bash_profile of user "root". That script executes when we do "sudo su -" and prompts with a question : "Why are you logginf as root?" and users have to pass the reason then they get prompt. Inside script we have used "read -p input" to take input from user.

I am a writing a script to check if this functionality works in all servers. Something like below-

Code:

_check_whyroot()

{

_check_why=`sudo su - 2>&1`

[[ $_check_why == *"Why are you logging in as root"* ]] && [[ $? == 0 ]] && echo "Checking Whyroot Script is working...Okay"  || echo "Checking Whyroot Script is working...Not Okay"

}

_check_whyroot

The issue with this function is that it waits for the input from user when they execute it because of "read -p command" inside bash_profile of root user. And I am also not able to pass the stdin to it forcefully in the script because "sudo su -" command spawns a new shell for root user.

Is there a way I can pass an input to this so I do not need to press "enter" or pass anything manually.

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
