I tried this as I have the same error messages as the John and opened a

So there is still a reference to an remote directory.

and I still get the error:

,----
| /bin/sh: 1: /scp:pogoplug:/tmp/sh-script-81150VZO: not found

Here I have:

,----
| Its value is "/var/folders/50/wcr5bjwn75q595n6x82gxj280000gn/T/"
