[Solved] Splitting comma set files

Question

This might work for you (GNU sed):

sed -r 's/^(.*\|.*\|)([^,]*),([^|]*)(\|.*\|.*\|)([^,]*),([^|]*)(.*)/\1\2\4\5\7\n\1\3\4\6\7/;P;D' file

Iteratively split the current line into pieces, building two lines separated by a newline. The first line contains the head of the 3rd and 6th fields, the second line contain the tails of the 3rd and 6th lines. Print then delete the first of the lines and then repeat till the lists in the 3rd and 6th fields are consumed.
