It isn't critical, I just took advantage of it since your sample input was always in this form.

Now I checked manually in all my files, except one value which is 5390.001, all other ends with .000
OK. So I have to do some arithmetic instead of letting awk treat 00.000 as a field separator.

As you suggested a good point, (even I have not thought of it Smilie ) regarding value 19,824.80 and three options:
(1) nothing to be printed,
(2) result of the division truncated to return the 19,824th entry, or
(3) rounded to return the 19,825th entry

So, I wish to retreive both entries 19,824th and 19,825 in one file as well as 3 other files with above options.
In the file with both entries, if the truncated and rounded entries are the same, do you want that entry printed twice, or just once? (For example, 5310.000 truncates to the 53rd entry and rounds to the 53rd entry.)
Quote:
That means for 1st field values that are non-divisible by 100, I wish to retreive one file containing nothing for them, one file with truncated, one file with rounded and fourth file with both truncated and rounded values (but each of these 4 files must have divisible entries too).


Thanks
  1. What names do you want for these four files?
  2. In the file that has both rounded and truncated entries, do you want any kind of marker added to the output entries indicating that there are two output record for a single input line? If so, what should the marker be?
  3. In the file with truncated and rounded entries, do you want any kind of marker added to the output entries indicating that the record from 11.txt was selected based on truncating a value or rounding a value, respectively? If so, what should the markers be?
  4. In the file with nothing for values that are not evenly divisible by 100, do you want any kind of marker in the output to show that an entry was skipped? If so, what should the markers be?
  5. Do you want one of these four files to be written to standard output, or do you want all output to be written directly to the four files?
If you want markers, it would be relatively easy to include markers of the form:
Code:
Following entry (%d) comes from %s truncated:
Following entry (%d) comes from %s rounded:
Entry skipped because %s is not evenly divisible by 100.

where the %d is replaced by the entry number of the following lines and %s is replaced by the 1st field in o.txt, if that is what you want.
