Hi Scott I found your utilities for POPFile and I have tested them with Perl running under GNU Linux --- everything worked as expected, thanks! Specifically I used Perl 5.8.0 on a Debian/unstable system with a (to my knowledge) standard Perl installation. I tested snapshot_stats, remove_ignorewords, topten, and pfdiagnose with POPFile 0.19.0 With snapshot_stats I played a bit with the -csv_separator option. It worked fine when I invoked the script as % perl snapshot_stats.pl -csv_separator ';' That is, the semi-colon has to be enclosed in quotes in my shell to prevent the shell from interpreting it as a separator between commands as in the command % echo foo; echo bar which runs the echo program twice. You can add that information to your web pages if you like. Thanks again! -- Martin Geisler My GnuPG Key: 0xF7F6B57B
