it might be funny but i thought Pal-Cod3r have diff requirement.

sub doit{
 print "How are you?\n";
 $x=1+1;
 print "$x\n";
}
open(FILE,"<monkss.pl");
@lines=<FILE>;
close(FILE);
open (FILE, ">files.txt");
$flag=0;
foreach $line(@lines)
{
 if($line =~ /doit\{/)
 {
  $flag=1;
 }
 if($flag)
 {
  print FILE $line;
 }
 if($line=~ /\}/)
 {
  $flag=0;
 }
}
close(FILE);
