As a side note, I see that you also posted this question on the shiny-discuss forum . Please see this post below from Hadley regarding cross posting. If you do it, you should link to your other posts so that people do not spend time answering your questions if they have already been answered.

How to call a shell script after clicking on a action button in R?

@RavinderSingh13 I notice that you also asked the question on stackoverflow without cross-linking the two questions. That's generally considered to be rude - someone might spend their time answering the question on SO when it's already been answered here. If you must ask in multiple places, please make it very clear that you've asked in multiple places, and once you have an answer in one place, make sure to update all of your questions.
