Sorry to reply to myself yet again, but I figured out what to do, and discovered a bug in GNU Parallel in the process.
The reason it wasn't working for me originally is because I was attempting to mix - m and --bar. This does not work. You must drop --bar to use -m. Then the equal distribution of the arguments will happen with e.g.: ⇒ find build/SVG_layers/ -iname '*.svg' | parallel -m 'inkscape --batch-process -- actions "select-all:all;verb:StrokeToPath;select-all;verb:SelectionUnion;export- plain-svg;" --export-overwrite' However, if you add --bar, it will not work, arguments are unequally distributed. I think this is a bug, but perhaps I just don't understand why it happens. Best, Fred Brennan
