Delete from one row and up in a txt file?

Post by ayu »

Could anyone help me to like, make or get a code/proggy that deletes everything from one row in a text document and up?

because i have dictionarys with 1500000000 words, and sometimes i want to delete everything from like row 80000 and up..and that takes time xP

Here's a PHP script:

Code: Select all

<?PHP

$file = file('dictionary.txt');

$open = fopen('newdictionary.txt', 'a');

for($a = 8000; $a < count($file); $a++)
{
fwrite($open, $file[$a]);
}

fclose($open);

?>

He just gave you the receipt to do it. Just read :wink:

[ This will work on any language, pick-up the one you like]

Open your wordlist ( File s )
Create a new .txt file ( File x)
For ( int i = 8000; ! s.endOfFile ; i++)
x = s(i);

Close all file.

This should work imo

Ps: I think gogeta used this strategy.

... If you don't understand the programming language, you shouldn't comment on it. Neo, when i said it 'read' from line 8000 i was saying that i rewrote the dictionary file, making line 8000 line 1.

Anyway tried the php code, and it doesn't work, it seems like it adds everything from row 0 to 8000 instead of deleting it. because the file was like 1 mb bigger now :?

If you open the php file multiple times, it'll append the data to the file, not overwrite it.
