Hi, this is with perl 5.8.7 and 5.8.8 on Linux. This code works as expected: 
find({wanted => \&wanted,},'/tmp');

sub wanted {
 print "$File::Find::name\n";
}

[download]
this works not as expected: 
find({wanted => \&wanted,
      preprocess => \&preprocess,
      postprocess => \&postprocess},'/tmp');

# wanted see above

sub preprocess {
 print "pre\n";
}

sub postprocess {
 print "post\n";
}

[download]
edit: and that is because I have not read the complete docs for "preprocess", but stopped after the first sentence. Oh my. See merlyns answer for a solution. if preprocess looks like this: 
sub preprocess {
my @dir = @_;
print "pre\n";
return @dir;
}

[download]
the code does "the right thing".

(there is no directory 1 in /tmp, and there are thousands of files) While the first code example willingly traverses my /tmp directory, the second one gives me a rather weird output: 
/tmp
pre
/tmp/1
post

According to the docs, I would expect to have preprocess and postprocess being called befor resp. after processing every directory, but the traversal should be not influenced by this. What am I doing wrong here? Or is it a bug?
