I need to some code that will get the current directory and then remove it from a directory listing that includes sub directorys. i.e:

current dir:
dir /s listing:
c:\perl\bin\aa.exe c:\perl\doc\bb.txt c:\perl\web\index.html
I need:
bin\aa.exe doc\bb.txt web\index.html
current unworking code:
open(GETDIR, "cd |"); while(<GETDIR>) { chomp; $currentDir = $_; } open(DODIR, "dir /b /s|"); while(<DODIR>) { chomp; $pathRemoved = $_; $pathRemoved =~ s/$currentDir//i; print $pathRemoved; }

I strongly recommend using File::Spec:

use File::Spec; $rel_path= File::Spec->abs2rel( $abs_path );
use File::Spec::Functions qw( abs2rel ); $rel_path= abs2rel( $abs_path );
You can also provide a second argument to abs2rel() that tells it to strip a directory other than the current working directory.

See also my review of File::Spec.

use strict; use File::Find; use Cwd; my $startDir=getcwd; find(sub {printf "%s\n", substr((split($startDir,$File::Find::name))[1 +],1) if ($File::Find::name ne $startDir);}, $startDir);
