Hello,
I had never used File::Find::Rule before, but I gave it a try.
ActivePerl 5.8.9 Build 826.
I set up a test with 3 files in the directory hierarchy:
D:/My Documents/projects/dave/test/should-print.txt
D:/My Documents/projects/dave/test/84-33 (Kland, Dan)/test.pl
D:/My Documents/projects/dave/test/84-33 Kland, Dan/test2.pl
Then ran the following code:
use strict;
use warnings;
use File::Find::Rule;
my $ctr = 1;
print "\n\n============== START =====================\n";
while (my $pattern = <DATA>)
{
chomp $pattern;
my $rule = new File::Find::Rule ();
my $subctr = 'a';
foreach my $modifiedPattern ( qr/\Q$pattern\E/, $pattern )
{
my @exclude = ($modifiedPattern);
print "\n=============================================\n";
print "== $ctr$subctr >>$exclude[0]<<\n\n";
$rule->or(
$rule->new->directory->name(@exclude)->prune->discard,
$rule->new
);
my @files = $rule->file->in('D:/My Documents/projects/dave/test');
foreach my $file (@files) {
print "$file\n";
}
$subctr++;
}
$ctr++;
}
__DATA__
Kland, Dan
(Kland, Dan)
84-33
84-33
84-33 (Kland, Dan)
84-33 Kland, Dan
84-32
This produced the output listed below

D:/My Documents/projects/dave/test/84-33 Kland, Dan/test2.pl
===== END OF OUTPUT ======
It appears that the parentheses are being ignored.
The following names, produce the same results.
And, they never seem to eliminate the directory with the parentheses.
== 5a >>(?-xism:84\-33\ \(Kland\,\ Dan\))<<
== 5b >>84-33 (Kland, Dan)<<
== 6a >>(?-xism:84\-33\ Kland\,\ Dan)<<
== 6b >>84-33 Kland, Dan<<
Also, the following should not have excluded the directory "84-33 Kland,
Dan", but it did.
== 2a >>(?-xism:\(Kland\,\ Dan\))<<
So, there does seem to be something amiss.
Ken
