Re: Finding directories at a variable depth

in reply to Finding directories at a variable depth

Here is a File::Find script which counts slashes to determine depth. Modify the depth and slash according to your needs.

#!/usr/bin/perl
# linux only, use appropriate \  for MSWindows
use warnings;
use strict;
use File::Find;
use File::Spec;

if (@ARGV < 2){print "Usage: $0 dir depth\n";exit}
my ($path, $depth)= @ARGV;

my $abs_path = File::Spec->rel2abs($path); #in case you enter . for di
+r
my $m = ($abs_path) =~ tr!/!!;  #count slashes in top path

find (\&found,$abs_path);
exit;

sub found{
 my $n = ($File::Find::name) =~ tr!/!!; #count slashes in file
   return $File::Find::prune = 1 if $n > ($m + $depth);
   return unless -d;
   # do stuff here.
   #print "$_\n";                #name only
   print "$File::Find::name\n";  #name with full path
}

This is just what I wanted zentara!

Thanks.

And if i wanted only directories of level 2 and not of level 1?

This is only briefly tested. The problem with only getting level 2 and not 1, is that you can't prune level 1, without pruning level 2. This script is only briefly tested, play with it. Instead of prune, use a simple return.

#!/usr/bin/perl
# linux only
use warnings;
use strict;
use File::Find;
use File::Spec;


my ($path, $depth)= ('.', 2);

my $abs_path = File::Spec->rel2abs($path); #in case you enter . for di
+r
my $m = ($abs_path) =~ tr!/!!;  #count slashes in top path

find (\&found,$abs_path);
exit;

sub found{
 my $n = ($File::Find::name) =~ tr!/!!; #count slashes in file
 print "$m $depth $n  ";

 return  unless $n == ($m + $depth );
 
   # do stuff here.
   #print "$_\n";                #name only

 print "$File::Find::name\n";  #name with full path
}
