We need to remove all / \ } { & $ # @ ~ ` pretty much anything that is NOT a letter or a number.

You can try something along the following lines:

fixdir('d');

sub fixdir {
    my $dir = shift;
    opendir my $DH, $dir or die "$dir: $!";
    while (my $f = readdir $DH) {
        next if grep $_ eq $f, qw/. ../;
        (my $new = $f) =~ s/[^a-zA-Z0-9_.]/_/g;
        die "$f: $new already exists.\n" if -e "$dir/$new" and $new ne
+ $f;
        print STDERR "Renaming: $f -> $new\n";
        rename "$dir/$f", "$dir/$new";
        fixdir("$dir/$new") if -d "$dir/$new";
    }
}

WOW - Thank YOU !!!! :-)

I have a question regarding this statement...

sub fixdir {
    my $dir = shift;
    opendir my $DH, $dir or die "Not Found....$dir: $!";
    while (my $f = readdir $DH) {
        next if grep $_ eq $f, qw/. ../;
        (my $new = $f) =~ s/[^a-zA-Z0-9_.]/_/g;
        next if ($new eq $f);   <<<<<<<<<<<<<   THIS ONE  <<<<<<<<<<<<
+<<<<
        while ( -e "$dir/$new") { $new.= "1";  }
        print STDERR "Renaming: $f -> $new\n";
        rename "$dir/$f", "$dir/$new";
        fixdir("$dir/$new") if -d "$dir/$new";
    }
}

IF $f is the name of a directory and not a file won't that whole direc
+tory get skipped?????

Thanks

Hello, This is my revised code. can anyone spot any blaring error??

#!/usr/local/ActivePerl-5.16/bin/perl

use POSIX qw/strftime/;
use strict;
use warnings;
use diagnostics;

sub fixdir {
    my $dir = shift;
    opendir my $DH, $dir or die "Not Found....$dir: $!";
    while (my $f = readdir $DH) {
        next if grep $_ eq $f, qw/. ../;
        (my $new = $f) =~ s/[^a-zA-Z0-9_.]/_/g;
        if (-e "$dir/$new") {
            fixdir("$dir/$new") if -d "$dir/$new";
            next;
        }
#        next if ($new eq $f);
        while ( -e "$dir/$new") { $new.= "1";  }
        print STDERR "Renaming: $f -> $new\n";
        rename "$dir/$f", "$dir/$new"; 
        fixdir("$dir/$new") if -d "$dir/$new";
    }
}

die "No command line arguments given!" unless @ARGV;

my $nargs = @ARGV;
print "Number of command line arguments is $nargs\n";

my $Do_Dir = $ARGV[0];
# print("ARG=", "$Do_Dir", "<<<<<<\n");
if (!$Do_Dir ) {
    print ("No Folder Name given!\n");
    exit; }
print( "The Folder Name is: ", "$Do_Dir", "\n" );
fixdir("$Do_Dir");
print "Done...\n"
