Wise Monks,
It's hard to say what I need, so I use some examples:
I have directiories:
/root
+dir1
+1a
+1b
+dir2
+2a
+2b
+2c
without exceptions my directiories list shoud look:
/root
with exception on /root/dir2/2b:
/root/dir1
/root/dir2/2a
/root/dir2/3a
So, I use some code from runrig on How do I recurse all *but* a few directories? and I've made this:
use File::Find;
my @abs_dirs = qw ( /usr/local/share/locale );
my %abs_dirs;
@abs_dirs{@abs_dirs} = ();
my @OK_dir;
my %all;
find(
sub {
$File::Find::prune = 1, return
if -d and ( exists $abs_dirs{$File::Find::name} );
my $dir = $File::Find::name;
return if -f $dir;
if ( ( grep { $_ =~ m/$dir/ } @abs_dirs ) and ( !exists $all{$
+dir} ) ) {
$all{$dir};
}
else {
push @OK_dir, $dir;
$File::Find::prune = 1;
return;
}
},
"/usr/local/"
);
It works, but I wonder if is any better way to do it? I dont't think about usless $all{$dir}, but about totally difrent way.
Thanks for your help and time,
greetz, Uksza
Yes, smart people know that fat arrow autoquotes the left argument. But why should you require your code to be maintained by smart people?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
