Re: Best way to compare two files

You can use backticks to send the files to the separate gnu utility diff, and get the results, or you can use a Perl module like Text::Diff

But you should be more specific in your question, like show us some sample code, or sample files.

Text::Diff (and it's model, GNU diff) won't selectively ignore things; the poster needs to compare, but ignore differences in date. Unfortunately, a simple diff won't accomplish this. One approach would be to load columnar data (date in one column) and ignore the date column while comparing the rest of the data using something like Array::Compare. radiantmatrix `require General::Disclaimer;` "Users are evil.

You are right, but I was thinking that the poster could do some post-processing of the diff output to discard the dates. I'm not really a human, but I play one on earth. flash japh	[reply]
