Do you always know the length of the file, and know which line you want to put it in? If so:

#!/usr/bin/perl -wT

use strict;

#get inserted text
my @inserted_text = ('Blah','Blah Blah');

# read in the file
open (FILE,"filename") or die "Can't open file";
my @file = <FILE>
close(FILE)

open (OUTFILE,">filename") or die "Can't open file";
my $line = 0;
foreach(@file) {
    if ($line = 569) {
       foreach(@inserted_text){print OUTFILE;}
     }
    $line++;
}
close(OUTFILE);

Otherwise, you could find out the length of the file, and then subtract 30 from the end of the length, and insert it there.

This is untested code and, I'd bet 70 monks here could give you much, much better answers. I look forward to seeing them.
