in reply to Regular expression to list all files of type in folder

Did you put a print "$file\n" before the "next unless" to see if the file even gets returned by readdir?

Also, unless you're using autodie, you should check the status of open and opendir.

    I skipped the "or die" checks because this is just a quick hack to populate the files I need to include in my PARPacker build list. I agree though this should always be done.

    I just checked on your suggestion and you are right, readdir is the one not picking up the similarly named files, though I have absolutely no idea why.

    There are no strange files present. No file named "0" or any weird symbols (not that it should matter). It is basically just a folder full of a couple hundred .jpg files with simple names.

    I'm using Perl 5.12 so the use in a while loop should be no problem.
      what do you get from

      print join "\t", <$dir/*>

      maybe you confused the path?

      'C:/Some/Random/Folder/tmp/bin' ne "C:\\Some\\Random\\Folder\\perl\\bin\\"

      Cheers Rolf

[marto]: maybe next year when the kids are a little older I'll have time to attend perl events in Europe
[Corion]: marto: Yeah - there isn't a Perl Day-Care at Perl events - we thought about it for YAPC::Europe 2012 but it's a gigantic effort to organize that
