There’s two common ways to do this, depending on what you need. If you need 
this to execute in response to a change in a different resource, such as a 
file being updated or a service restarted, then you want to use `action 
:nothing` and have the other resource notify your execute resource to run. 
See: http://docs.opscode.com/resource_common.html#notifications

If your execute resource is more like a “poor man’s LWRP”, that is, it 
independently manages some system state unrelated to other resources, then 
you can use a guard command to make the execution conditional based on 
results of that command. See: 
http://docs.opscode.com/resource_common.html#guards
