Hi Monks I'm having some issues with trying to get a substitution working or to think of another method to do what I need done. I have the following code

 

find(\&all, @allpaths);
    open (LIST, ">$filepath/Paths.bak") or die "$! error trying to ove
+rwrite"; 
    foreach my $p (@allpathlisting)
    {
        print LIST "$p\n"; 
    }
    close LIST; 
    copy $allpatholdfile, $allpathnewfile or die "$! error trying to c
+opyfile"; 
                
sub all {
    return unless -d; 
    $File::Find::prune = 1 if /[IPDLMY]\d{8}$/;  
    (my $fn = $File::Find::name) =~ tr#/#\\#; 
    push @allpathlisting, $fn if /[IPDLMY]\d{8}$/; 
    print "$fn\n" if /[IPDLMY]\d{8}$/; 
    foreach (@allpathlisting) 
        {
            s/gpfs_data/nas\/rdds/;
        }
}

I want to replace /gpfs_data/ with /nas/rdds/ I'm wondering if the code below

foreach (@allpathlisting) 
        {
            s/gpfs_data/nas\/rdds/;
        }
[download]

Could be added somehow to

(my $fn = $File::Find::name) =~ tr#/#\\#;
[download]

Because my script is taking a bit longer to run now and I can't get Perl to replace the / with \ in this bit /nas\/rdds/

Sorry for the formatting, I had comments at the ends of lines but pasting it here made the code all weird
