No. It's used as

YES, be aware of the strike through.
[QUOTE]However I cannot understand why we need counter+=NF in this case, as NF should be 16. Can you please explain this logic? [QUOTE]
The
counter in fact is a pointer into the file, starting at the zeroth byte, then at the 16th, etc. Thus adding the line length (better: line's byte count) keeps the pointer pointing to the correct file position.

Can we use something else to accomplish this (i.e for loop).
What?
