.
What I need is:
[login to view URL] contains number x data records (1 per line) CSV format
[login to view URL] contains number y data records (1 per line) CSV format
The needed script shall be able to do the following in each of the files
1) sort records in ascending order
2) delete duplicate records
Option 1
- add both files into one file [login to view URL]
- delete duplicate records in [login to view URL]
- after [login to view URL] has been filled the original two files are to be deleted and after that [login to view URL] should be renamed to become [login to view URL]
Option 2
- delete all records in [login to view URL] that are contained in [login to view URL] too and build [login to view URL] with the remaining records of [login to view URL] after operation
- after [login to view URL] has been filled the original two files are to be deleted and after that [login to view URL] should be renamed to become [login to view URL]
The size of the records in each .txt file can be huge (100.000 and more)
For an experienced C/C++ or Delphi programmer this should be a matter of a couples of hours to program. I do not need an elaborate User Interface. Just a simple Windows style selection and data entry interface.
Thanks for your bids
