in reply to Ignoring a Directory with File::Find

Specify a 'preprocess' routine and filter the directories:

find( {
    wanted => sub { ... },
    no_chdir => 1,
    preprocess => sub { grep not m/$dir/ => @_ },
},
   $search_root
);

    fruiture,

    Thanks for the reply (as well as everyone else). I tried your code in my script as such: 
    # Build a Regex

my $rexstr=join'|',map {quotemeta $_} @exts; 
my $rex=qr/(?:$rexstr)$/i;

# Directory to Ignore 

my $dir = qr/pics/i;

my @list;

# Find the files
find({ 
      wanted =>sub{ print "Found a match: $_\n" if /$rex/; 
        push @list,$_ if /$rex/} , 
        no_chdir => 1, 
        preprocess => sub { grep not /$dir/ => @_ },
      }, 
      $search_root
    );

    but I'm getting the error: 
    Not enough arguments for grep at test.pl.txt line 30, near "@_ }"
Execution of test.pl.txt aborted due to compilation errors.

    I think my syntax is correct. I did end up taking John M. Dlugosz and FamousLongAgo suggestion and use a blank return statement instead and I got it to do what I want. I'm still curious about this preprocess function though. I could not find any mention to it in the File::Find docs. nor in perlsub Where can I read more on this function?

    Also, I went back and read my node and in my text, and  next if $string, should have read  next if $dir. Hope that didn't confuse anyone.

    Thanks,
    Dru
