Have a list of words - need a program to delete words longer than 11 letters

I have a list of 200,000 words in a text file and am looking for a program to run through and delete the words that are longer than 11 letters. It's pretty simple but is there one out there?

 

$file = fopen('textfile','r');
while($tot = fread($file,125647)){$content .= $tot;}
fclose($file);

$lines = explode($content,"\n");

$new_file = fopen('newtextfile','w');

foreach($lines as $line){
    if(strlen($line) <= 11){ fwrite($new_file,$line."\n");}
}

fclose($new_file);

PHP:

Peace,

 

Use a regular expression find/replace on dreamweaver, textpad or other programs supporting regular expressions

find: "^.{12,}$"
change all occurences to : "" or "whatever you want"

dont type the quotes
