POPFile corpus_diff Utility

This utility is deprecated and no longer supported. It will not function properly with versions higher than 0.20.x.

The corpus_diff utility is a POPFile tool intended for developers or those advanced POPFile users who wish to analyze the difference between a reference corpus and the current corpus. The diff will show all deleted, changed and added entries.

The utility is not intended for the casual POPFile user. It requires a good understanding of using command line programs, the directory structure, and of how to copy files from directory to directory.

Corpus_diff is compatible with versions 0.19.0 or higher of POPFile.

POPFile is an automatic email classification tool authored by John Graham-Cumming available from SourceForge.

Instructions for use

  1. Download the script;

  2. Create a reference corpus by copying your existing corpus folder to a folder named corpus.bak (replace the word corpus with the name of your corpus folder if you changed it from the default. This reference corpus will be the corpus that corpus_diff compares against.

  3. After reclassifying mail, you can, at will, run the corpus_diff utility to see the changes since your referenece corpus.

    • Open a DOS box and change to your POPFile directory.

    • run corpus_diff 

      perl corpus_diff.pl > diff.htm

    • View the results via your browser, either browse to your POPFile directory and open diff.htm, or, type 

      start diff.htm
