Hey,
thanks for developing this. However, I cant run diff, because it somehow can't find my script and I get this error after perftree ./script.sh:
cannnot compute diff: %1 is not a valid win32 application (os error 193)
But when I run my script in the same terminal with ./script.sh 3 "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1" I get the desired result.
I also tried with all variations of backslashes/fullpath/ etc., which all lead to some errors.
