Description:

I am using:
open FILES, "dir /b /aa /s |" or die; while(<FILES>) { #process result } close FILES;
On NT this gives me a list like:
C:\WINDOWS\INF\wordpad.inf C:\WINDOWS\INF\wordpad.PNF C:\WINDOWS\INF\WPIE3x86.INF C:\WINDOWS\INF\WPIE3x86.PNF . . .
How do I split this string into two parts, the directory path and the filename?

The File::Basename module is probably what you want.

use File::Basename; ( $name, $path, $suffix ) = fileparse( $filename_with_path, "\.[^.]*" +);

The File::Spec module will let you separate the volume, without having to worry about the suffix:

use File::Spec; ( $volume, $directories, $file ) = File::Spec->splitpath( $path );

You should consider solving your problem in a different way. By using the opendir and readdir functions to get the entries in a directory, you automatically have the filename separate from the directory name, and you can do it all without spawning an external process.

open FILES, "dir /b /aa /s |" or die; while ( <FILES> ) { my( $dir, $file ) = /(.+)\\(.+)/; defined $file or next; # no path separator print "$dir => $file\n"; } close FILES;

This works for both DOS and UNIX path separators and when there is no path info.

( $dir, $file ) = m/(.*)[\\\/](.+)/ ? ( $1, $2 ) : ( undef, $_ );
