You have to run a single pipeline over each file in a script and substitute as appropriate

Are there additional wildcards or code that needs to be included/not included in the *.json?  I am working in Docker and coding within my container using the script found on the pdal.io website "Loop a directory and filter it through a pipeline" as a template.  Thanks for any help.      


Can you post some of your pipeline examples? I presume you are talking about http://www.pdal.io/tutorial/reading.html?highlight=loop#loop-a-directory-and-filter-it-through-a-pipeline which will need some modification to work if you are using Docker and windows.
