monitor folder and execute command

Question

I'm looking for a solution for monitoring a folder for new file creation and then execute shell command upon the created file. The scenario is I have a host machine that runs a virtual machine and they share a folder. What I want is when I create or copy a new file to that shared folder on my host machine, on the VM, the system should be able to detect those changes. I have tried incron and inotify but they only work when I do the copy, create as a user in the VM. Thanks

Method 1 in this answer may help: Bash script, watch folder, execute command
Just run that script in your VM, and you should be able to detect changes made by the host.
