webpack --display-modules | awk '{print $2}' | grep ^\.\/ > files-processed.txt;
cd src; # assumes all your files are here
find . -name *.js?(x) | grep -v eslint | grep -v __ > ../../files-all.txt; # excludes __tests__ and .eslintrc files
cd ..;
cat files-all.txt | xargs -I '{}' sh -c "grep -q '{}' files-processed.txt || echo '{}'";
