file manipulation help needed

[dulux]

Hi all,

I have the following problem and a partial solution.

I have a folder - lets call it A. Within A, I have numbered folders 0-19. I have managed to open all the folders and made them ready for the rest of the operation.

I have a separate folder, called IMAGES, full of JPG's.

I need to open the IMAGES folder (okay so far), then read all the image filenames into an array (trouble brewing).

I am trying to use the following code, but get an error message -

---------------------------------------------------
if(opendir(IMAGES,$imagepath))
{
print"\nopened Converted Image folder okay\n";
}
else
{
print"\n did not open Converted Image folder";
}
while(<IMAGES>)
{
@array=<IMAGES>;
}

-----------------------------------------------------
The error is 'readline() on unopened filehandle IMAGES'

I thought I had opened the file!

I then need to check the name of each image - the name will be numeric - and depending on the result copy the image to one of the numbered folders. The checking of the name is no problem.

Any help is much appreciated - and have a Merry Christmas

while(<IMAGES>) {...}

The <> operator expects a filehandle, not a directory handle (I think - I couldn't find a definitive reference in 60 seconds of searching).

Keep in mind that there's more than one way to do it, but when I have to process all files of a particular type in a directory, this works for me. I used &quot;jpg&quot; as my file extension. If your filesystem is case-sensitive, please adjust accordingly, and if you want to process all files, simply using &quot;*&quot; in glob() should work.

while(defined($filename = glob(&quot;<path goes here>/*.jpg&quot {

[do something with filename]

}
