Shane O’Neill takes us through some of the intricacies of dot-sourcing in Powershell:
The dot used to represent the location is, as I’ve said before, for the current location. Our
ConvertTo-Message02script changed it’s location as part of the script.When we used the “dot source dot location” method, we weren’t using where our function is as a frame of reference to import the other functions. We were using what directory we are currently in.
Interesting reading.
