in reply to quickest way to find number of files in a directory?

Probably something along these lines:

my $dir = 'directory name goes here';
my @files = <$dir/*>;
my $count = @files;

    Nit-picking: the dot files (like ".bashrc") are not counted when using the glob.

      That depends on your shells. At least under bash, you can use glob() to grab dot files, for example: 
        print "$_\n" for grep{ -f } glob(".*");
      Or probably if you want to grab both dot and non-dot files: 
        print "$_\n" for grep{ -f } glob("{*,}.*");

        Nope. It does not depend on your shell. At least not if you're using Perl 5.6 or later, because glob is implemented via the standard File::Glob extension and does not rely on shell anymore.

        The standard behavior of <*> or glob('*') is to not consider the dot files.

      is it efficient with more than 100 000 files in the directory ? if I well understand the code, each inode is loaded in memory... so do you know another mean to get this count, without need of a huge memory ?

    That also fails if $dir contains spaces or other glob meta characters.

    That works very nicely, thank you.

      Some people use whitespaces in paths. Try: my @files = <'$dir/*'>;

    Thanks a lot, that works great. Does anybody know if it's possible to include variables in the file handle? For example, if I want all the .pl files starting with 'blabla' is it possible to do something like this: my $prename = 'blabla'; my @files = <$prename*.pl> my $count = @files It works with just <*.pl> but I can't get the variable to work.

        Yes, it was mistake on my part - it works with variables, too. Sorry about that.
