guys.. anyone can suggest on my query please?

I need to make a utility to checkout code from Unix DEV Env to Test Env. I want to use HTML 5 in frontend to call the procedures in Unix.

I am not sure on how to approach towards coding the functions which calls the fucntions of Unix and establish the connection between HTML and Unix

For Ex: I would ask user for entering Env Name, Checkout path and code should be checkout out giving successful or unsuccessful message...
