Instead of changing the code, allow the user to pass some options in. If tachyon would be so kind as to allow me to lift his code: 
use strict;
use warnings;
use File::Find;
use Getopt::Long;

use vars qw($all @datein @exts @excl $base);
GetOptions(
   'exts|t=s' => \@exts,
   'excl|c=s' => \@excl,
   'base|b=s' => \$base,
   'all|a'    => \$all,
);

if (not $all) {
   @exts = qw( jpg gif tar gz bat txt ) unless @exts;
   @excl = qw( winnt cygwin ) unless @excl;
}
$base ||= '/cygwin';

my $exts = join '|', map{quotemeta} @exts;
my $excl = join '|', map{quotemeta} @excl;

find( sub { 
      push @datein, $File::Find::name
         if !$exts
         or m/\.(?:$exts)$/oi
         and $File::Find::name !~ m!/(?:$excl)!oi
      ;
   },
   $base,
);

print "$_\n" for @datein;

Now you can call the script like so: 
./find.pl -exts=txt -exts=gif -excl=nodes -base=.
or this if you want everything: 
./find.pl -base=/ -all
If specifying the extensions one at a time becomes too tedious for you, you can rewrite the code to allow the user to pass a delimited string instead. Read up on the Getopt::Long docs for more info. Additionally, check out the Unix command find.
