[pdal] [EXTERNAL] Re: loop a directory through a pipeline

[Smith, Michael ERDC-RDE-CRREL-NH CIV]

Howard, Michele,

Can't you also use something like xargs?
 eg:   ls *.laz | xargs -I{} pdal pipeline mypipe.json
--readers.las.filename={} --writers.las.filename=/my_new_dir/{}

If using this via docker, just get into the container to run this.
