Dear Most Intelligent Monks,

Please have patience on this confused novice with such a basic question. I am probably mixing up my punctuation and syntax to be honest.

I have chatted with many and read many nodes in my quest for the recursive directory copy all the .TXT (text files) to a single target i.e. a Perl program that goes into every subdirectory and copies all the .TXT files into a single target directory. There are no non-unique files (no duplicates). This is going to be run in MS-DOS so I have to follow the proper nomenclature. I have looked at http://search.cpan.org/~dmuey/File-Copy-Recursive-0.38/Recursive.pm and unfortunately it copies the entire directory structure to the target directory when actually I just want the files and not the source structure.

So after going through various implementations based upon PerlMonk nodes and on the web I came up with the following


#!/usr/local/bin/perl -w


use strict;
use File::Find;
use File::Copy;

my $sourcedirectory = $ARGV[0];
my $targetdirectory = $ARGV[1];

copyfiles();
sub copyfiles()
  {
     #the $sourcedirectory below tells the find where to start
     #looking for files.  The .TXT tells it only to return the files 
     #with the path if the file is a .TXT file. It then uses the copy 
     #of File::Copy to copy the entire path\filename to a SINGLE 
     #directory target.
    find(sub
           {
            copy
              ("{
               win_path{$File::Find::name$/"
               if(/\.TXT$/)},"$sourcedirectory")
              }
            ,"$targetdirectory");
           }
 }
 # ruzam figured out the following line on
 # how to convert the resulting string to MS-DOS complaint format   
sub win_path
{
(my $path = shift) =~  s![\\/]+!\\!g;  return $path; 
}

So it should be the same as if I had the following on the c: drive:

c:\20090127\A\01.TXT
c:\20090127\A\02.TXT
c:\20090127\B\03.TXT
c:\20090127\B\04.TXT
c:\20090127\B\05.TXT
c:\20090127\C\06.TXT

Running the perl program from the command prompt: 

C:\>perl program.pl c:\20090127\ C:\targetdirectory\

[download]

Would result in the following to be found in the directory in c:\targetdirectory\

c:\targetdirectory\01.TXT
c:\targetdirectory\02.TXT
c:\targetdirectory\03.TXT
c:\targetdirectory\04.TXT
c:\targetdirectory\05.TXT
c:\targetdirectory\06.TXT

Thank you for you patience for my very long winded question!!! I do appreciate it very very much!!!
