Try introducing an extra column 1, that contains the number of words in column 3, then sorting on that column and then removing the extra column, for example:
awk -F', *' 'NR>1 && NF{print...
awk can do that. Try:awk '$4~/^[Cc]/' t21bThe field separator here is comma-space so I would be inclined to use that:awk -F', *' '$3~/ [cC]/' t21bNote that these approaches only work if all...
