Specify Datastore path with ovftool???

All,

I am using ovftool to import ovf directly to ESX host using following command:

/usr/bin/ovftool --machineOutput <ovf-file> vi://user:pass@ip

It creates the vmx on ESX under the datastore path. But I want vmx files to be created under some directory in Datastore path. How? as ovftool says:

"When connected directly to an ESX host, <searchTerm>  must be left empty"

e.g   /usr/bin/ovftool --machineOutput <ovf-file> vi://user:pass@ip/<some-dir>

However the above command give me some syntax error.

Looks very trivial problem, But I could not found any solution yet.

Any comments/suggestion????

Thanks
