You must find a way to split a line into fields and then be able to say "sort on field N"

I don't have my copy of K&R here. I think it means this

Suppose the original file has

0000087423 Volkswagen 2001-01-01
0000642396 Fiat 2002-02-02
3900063521 Renault 2003-03-03

It is already sorted by the 1st field; if you want to sort it by the 2nd field (the name) the result would be

0000642396 Fiat 2002-02-02
3900063521 Renault 2003-03-03
0000087423 Volkswagen 2001-01-01

Or you can sort by date (the 3rd field)
