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.

NAME

       script-email - Amanda script to send email notifications

DESCRIPTION

       script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the
       addresses specified in the MAILTO property.

PROPERTIES

       This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API,
       script configuration.

       MAILTO

	   List of email addresses that will receive an email on command execution. It is a multi-valued property:
	     property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com"

EXAMPLE

       In this example, script-email is scheduled to be run before the DLE, on the server.  The unqualified email address amanda will be passed to
       the email system unchanged.  The script is then attached to a dumptype, which can then be specified for any DLEs which require
       notification.
	define script-tool pre-email {
	  comment "email me before this DLE is backed up"
	  plugin  "script-email"
	  execute-on pre-dle-backup
	  execute-where server
	  property "mailto" "amanda"
	}

	define dumptype user-tar-email {
	  user-tar
	  script "pre-email"
	}
