Dear Monks,
I'm making a little script with the simple Imager module.
I'm processing my images to resize them, and when the width is minor than the height I open the image with Gimp to make a simple transformation. I read all the images in my directory with:
opendir THIS, "." or die "Error: $!";
my @allimages = grep /\.jpg$/i , readdir THIS;

[download]
and after Gimp processing, I rename these images (temp_$number.jpg), and again the code is:
my @renamedimages = grep /^temp_\d\d+\.jpg$/i, readdir THIS;

[download]
but @renamedimages is empty.
It works if I write closedir THIS; after the first readdir, and after reopen with opendir. Why?
Is it impossible to have one opendir, many readdir and finally one closedir?
In Perl Programming, section Functions, there's a description for these functions, but this problem is not resolved.
Thanks
