Hi all,
I need a help(Urgent).
I would like to read the folders and files from my root directory.
The root directory contain subfolders and subfolders contain subfolders and/or files.
I need to read the contents from the folders/files and stored in variables.
I started coding like this:

#!/usr/bin/perl
print "Content-type:text/html\n\n";
$userDir="/usr/fweb/ourwebb";

$userDir="/usr/fweb/ourwebb";

########Read directory
if(opendir(USER_DIR, $userDir))
     {
          while($dirlist = readdir(USER_DIR))
          {
               print $dirlist;
          }
     close(USER_DIR);
     return 1;
     }

}

Note: While printing the $dirlist, showing the folders as ...logs_suntest3_sureshpFostersRobinShannonsRockwells(starting with .(dot)--for first entry one dot,next 2 dot)

Eg:Say if My root directory contain  folders as ONE,TWO,THREE,FOUR.
Folder ONE contain subfolder ONE1,ONE2 and a demo.txt file. The subfolder ONE1 contain foot.txt file.
Folder TWO contain subfolder TWO1 and b.txt file. The subfolder TWO1 contain TWO12 folder. The subfolder TWO12 contain game.txt file.
Folder THREE contain list.txt file.
Folder FOUR contain xy.txt file.

ie:
ONE -->[ONE1-->(foot.txt),ONE2,demo.txt]
TWO -->[TWO1->(TWO12->game.txt),b.txt]
THREE --> list.txt
FOUR -->  xy.txt

How can i solve this problem? Need a perl code to solve this problem.
I don't have any idea to read the subfolder contents. Please help me to solve this problem as early as possible.

150 POINTS WILL BE AWARDED.

Waiting for the soln.

You have to make a recursive function. As parameter, you have to give the subdirectory, so that you can call it again in the function itself, with another subdirectory.
You can check for a directory with the -d option.

if ( -d $dirlist )
{
   # call your function again with the $dirlist as parameter
}
else
{
   # it's a file
}

Be sure to check if the directory is empty!

I'm going to make such a function, but that will be after the final exams (so if you have time, wait until 27 june).

Sureshp, the code from ozo works perfectly (I tried it here on Win32 with ActivePerl, and it does it's job). Try copy and paste.
And, instead of print ... try $array[i] = $File::Find::name;

ToniVR,
Ozo's code is working. But i cannot store the first folder value in a variable. My requirement is different.
Anyway i used a lengthy code and finished that work.
Thanks a lot.
