Ubuntu Security :: How To Add User Password In Shell Script

I'm currently creating a simple sh file which will copy the contents of a certain directory to / directory. in my sh file:

Code:

cd "$DIR"
for i in *.*; do
sudo cp -iv "$i" "$DEST"
done

but this requires user password. can i add the user password in my sh file? how? I'm trying to do this because I have an application to run the sh file and the application has no way to enter the password..
