You might help us help you better if you could provide a better description of the problem you want to solve. I suggest that you:
- Give us a psuedo code version of the algorithm you want to implement
- Specifiy what the data files contain
- note any special knowledge like you need the value of some field that appears in a line before you reach the line that tells you that you need it
- specify what set of information completes a data set
- specify the output format
- specify what is fixed information and what is variable

Hello,
is it possible to debug a script that is already running "on-demand"?
Somehow a command like "set -x" but once you've executed the script. And another one to disable debugging?
