in reply to How to Get the Last Subdirectories

Hi bichonfrise74,

I would just use opendir and readdir recursively to scan the subdirectories yourself, and save the subdirectory only when it doesn't contain any subordinate subdirectories.

For example:

use strict; use warnings; use FileHandle; my $h_dirs = terminal_subdirs("/tmp/a"); my @dirs = sort keys %$h_dirs; print "Terminal Directories:\n", join("\n", @dirs); sub terminal_subdirs { my ($top, $h_results) = @_; $h_results ||= { }; my $fh = new FileHandle; opendir($fh, $top) or die "Arrggghhhh -- can't open '$top' ($!)\n" +; my @files = readdir($fh); closedir $fh; my $nsubdirs = 0; foreach my $fn (@files) { next if ($fn eq '.' or $fn eq '..'); my $full = "$top/$fn"; if (!-l $full and -d $full) { ++$nsubdirs; terminal_subdirs($full, $h_results); } } $nsubdirs or $h_results->{$top} = 1; return $h_results; }

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
