Not able to run .sh file from windows docker container. bash is present but not taking any effect

I have built image on top of microsoft/windowsservercore using dockerfile. Docker image is created successfully. I need to run .sh file after logging into windows container. However i am not able to run any .sh file. If i run .sh file, nothing happens.

c:\WorkSpace\dbscripts>bash init_db.sh

c:\WorkSpace\dbscripts>

bash is present on container as Git is installed.

c:\WorkSpace\dbscripts>where bash
c:\git\bin\bash.exe

Is there any way by which i can run .sh files inside windows container ?
