in reply to memory problems parsing large csv file

Basically you do a three level sort where lower levels are used to disambiguate ties. A more effective wheel was invented some decades ago: 
sort -k 9 -k 32 -k 33 <other options> <infile >outfile

Edit: -d is the field delimiter for e. g. cut, but not for sort.

    Wouldn't you also need to specify -t,?
