- Please use <code> around your code blocks. *grin*
- Glob calls the shell to do its expansion. Thus you will not get a cross platform
way of searching for files with it. command.com's "all files" is *.* In unix, that would mean getting all the files with a . in their name
which could be less than the total number of files.
A unix version of the code you had before would be
use strict;
my $directory = '.';
print "\n\n";
print CountSize($directory);
print "\n\n";
sub CountSize {
my $directory = shift;
$directory .= "/*";
my ($ask, $filesize,$item, $size, @raiz);
@raiz = glob($directory);
foreach $item (@raiz) {
$ask = -d $item;
if ($ask) {
$size += &CountSize($item);
} else {
$size += -s $item;
}
}
return($size);
}
However, this is not the "right way" to do this. You should be using opendir and readdir.
use strict;
my $dir = '.';
print &dir_tree_size($dir) . "\n";
exit 0;
sub dir_tree_size {
my $dir = shift;
my ($i,$total);
$total = 0;
opendir DIR, $dir;
my @files = grep !/^\.\.?$/, readdir DIR;
for $i (@files) {
if(-d $i) { $total += dir_tree_size($dir . "/$i") }
else { $total += -s $i}
}
return $total;
}
Hope this helps.
