It is a GEGL operation and not scriptable (as yet) as a Gimp script-fu/python-fu For GEGL functions you can check, as example: http://gegl.org/operations/gegl-shadows-highlights.html For lots of files you need (1) an up-to-date GEGL installed (2) a bash/batch file to run the command. You can always check the syntax of the command in Gimp. Use the "/" search + gegl to find gegl-graph, then enter the parameters. screenshot attached.
