How to perform a local shell command in OpenStack HOT template file?

The user data section in HOT is to run shell command on new created nova instance, however, I want to run a local(the machine which runs heat stack-create command) shell command when perform "heat stack-create" command.

But after I read though the OpenStack HOT doc, I didn't find any syntax to support this.

There is no syntax to support this. Heat templates are processed on the server. There is also no guarantee that the submitting system even has a standard Unix shell (heat templates can be submitted via a web browser, or with tools other than the heat CLI).

If your deployment workflow requires coordinating some local action with the Heat deployment, your best bet is to use another tool (Ansible? A shell script?) to automate the workflow.

An alternative would be to have Heat (or your VMs) signal your local system using some sort of web hook, and have a web service running locally that would receive the signal and perform whatever action is appropriate.
