Having re-read my post I was a bit blunt yesterday. On my computer I can't unzip a file with the wrong file extension.
I have written one-off searches of large numbers of reasonably large compressed text files in Shell and realise the practical limits. On your scale this is not a job for Shell programming.
This data came from somewhere and I would be very surprised if it only ever existed as a flat file. I suppose that you might be trying to find data rejections in context?
I am very concerned that this now appears to be a fuzzy search. The length of the search string and the position and size of the searchable data varies between your posts. This makes the software design so much more difficult and I withdraw any implication that this task is feasible.
On more reflection strongly advise that you get a Systems Analyst and a Database Designer on this job with view to possibly using a database approach. To my mind it is too early to engage a Database Programmer.
