After following this thread for a week my view is unchanged. You cannot capture transient data reliably from transient data files using standard unix tools.
Imho 1.The system design needs attention. In particular the application which is writing these data files. You get a completely different scenario if the application writes files with unique file names and closes each file after processing.
Imho 2. This processing should be in the primary system. Too many times we find complex data processing in Shell tools which should be done in a high level database language.
Throughout this thread we have learnt absolutely nothing about the process which writes these transient data files or the reason for intercepting the files and we have seen no sign of test code, formal testing, and the results of such testing.
Imho 3. This thread is a complete waste of technical resources.
