I have about 5 files, with 10-15 fields each. I would like to identify which fields are null and how many times each null field occurs in the files.
Using a variant of
s/(\||\)/$1/
I believe I could discover how many null fields are in each line, but that will not identify which nodes are null. I looked at awk, but I didn't find a variable there to identify which field it is processing. Thank you for your help.
