A small gotcha with cfexecute

This might get alot of people when running cfexecute consider this simple example of passing the result of the command dir back to ColdFusion:

<br /> <cfexecute name="c:\windows\system32\cmd.exe" arguments="/c dir #expandPath('.')#" variable="dirResult" /><br /> <cfdump var="#dirResult#" /><br />

It won't work. Why not? Because timeout is missing. It won't error on the cfexecute call but it will never get a result so dirResult wont exist.

<br /> <cfexecute name="c:\windows\system32\cmd.exe" arguments="/c dir #expandPath('.')#" timeout="10" variable="dirResult" /><br /> <cfdump var="#dirResult#" /><br />

While my example is Windows specific the timeout attribute is required when calling *nix command aswell.
