| A more efficient way of getting a directory listing? |
You might have noticed no comments are visible yet. I've actually got four to publish, but I'm just finishing off the display side of the system now (there was an afternoon nap that got in the way of that). Anyways, my current problem is that:
open FH, "ls /home/mikal/blog-comments/$path/$filename/ 2> /dev/null |" or die "Couldn't get a list of files";
Is terribly inefficient and slow. Is there a faster way of getting a listing of a directory's contents in perl? [tags: directory listing slow]

you're looking for opendir and readdir
opendir(DIR, $some_dir) || die "can't opendir $some_dir: $!";
@dots = grep { /^\./ && -f "$some_dir/$_" } readdir(DIR);
closedir DIR;
(that's from the readdir perldoc page, you'll need to modify it slightly)
