Example of providing auto input to a waiting shell process

In this instance pipes "y" to the called process to confirm we want the blog deleted.

(let ((delcommand  (format "yes y | google blogger delete --blog '%s'  --title '%s'"  googlecl-blogname  btitle)))
                      (message "Delete command is : %s" delcommand)
                      (call-process-shell-command delcommand))
