Hi

sorry if this a trivial question, but I'm relatively new to perl...
anyway, here it is:

I'm writing a script what uses directory/files structure to build a multi-level hash. here's the test code I've tried to use:

#!/usr/bin/perl -w

use diagnostics;

my $source_dir = "/home/haim/tmp/lists";


sub init_source_list {
   chdir $source_dir or die "Cannot change dir to $source_dir! ($!)";
   while (defined($sourcefile = glob("*"))) { # for every file in this
                                        # directory
      if (-d $sourcefile) { # if the file is actually a directory...
     while (defined($ver = glob("$sourcefile/*"))) {
        #$ver =~ s/.*\///; #remove everything before the "/".
        $apps{$sourcefile}{$ver} = undef; # add an empty key to
                                              # %apps{$sourcefile}
     }
      } else {
     $apps{$sourcefile} = undef; # add an empty key in the hash
                                     # %apps
      }
   }
}


&init_source_list;
foreach $key (keys %apps) {
   if (keys %{ $apps{$key} }) {
      foreach $vkey (keys %{ $apps{$key} }) {
     print "$source_dir/$key/$vkey\n";
      }
   } else {
      print "$source_dir/$key\n";

   }
}

if there are no spaces in the folders/files names then, everything is ok. the problem starts when one of the directories have spaces. below there are the correct tree and the tree I've got from this script:

Correct:
/home/haim/tmp/lists/png.list
/home/haim/tmp/lists/patches.list
/home/haim/tmp/lists/icon-list
/home/haim/tmp/lists/tcl
/home/haim/tmp/lists/test1
/home/haim/tmp/lists/test2
/home/haim/tmp/lists/test3/ver2
/home/haim/tmp/lists/test3/ver1
/home/haim/tmp/lists/test4
/home/haim/tmp/lists/a b/ver 2
/home/haim/tmp/lists/a b/ver1-default
/home/haim/tmp/lists/test5
/home/haim/tmp/lists/test6/ver2
/home/haim/tmp/lists/test6/ver1
/home/haim/tmp/lists/test7
/home/haim/tmp/lists/packages

The Actual result I've got:
/home/haim/tmp/lists/png.list
/home/haim/tmp/lists/patches.list
/home/haim/tmp/lists/icon-list
/home/haim/tmp/lists/tcl
/home/haim/tmp/lists/test1
/home/haim/tmp/lists/test2
/home/haim/tmp/lists/test3/test3/ver2
/home/haim/tmp/lists/test3/test3/ver1
/home/haim/tmp/lists/test4
/home/haim/tmp/lists/a b/a
/home/haim/tmp/lists/test5
/home/haim/tmp/lists/test6/test6/ver1
/home/haim/tmp/lists/test6/test6/ver2
/home/haim/tmp/lists/test7
/home/haim/tmp/lists/packages

* note the "a b" directory and the test3/test6 directories.

As a workaround I've used 'chdir' to every directory:

sub init_source_list {
   chdir $source_dir or die "Cannot change dir to $source_dir! ($!)";
   while (defined($sourcefile = <*>)) { # for every file in this
                                        # directory
      if (-d $sourcefile) { # if the file is actually a directory...
     chdir "$sourcefile";
     while (defined($ver = <*>)) {
        $ver =~ s/.*\///; #remove everything before the "/".
        $apps{$sourcefile}{$ver} = undef; # add an empty key to
                                              # %apps{$sourcefile}
     }
     chdir "$source_dir";
      } else {
     $apps{$sourcefile} = undef; # add an empty key in the hash
                                     # %apps
      }
   }
}

this one has solved the problem but it's not a very alegant solution.
I was wondering if there is a solution for that (I'm using perl 5.6.1 on both solaris and linux)?

thanx
