in reply to how do i reset a filehandle?

I say that this can be handled many ways. My favorite is to read the whole file into a string/array/hash to then do search and replace and testing of the text. 
open(INFILE, "infile.txt");
my $filesize = -s INFILE;
read(INFILE, $temp, $filesize);
close(INFILE);

$temp = /(regex here)/;

and your other stuff here

    This gets really bad when you have to deal with large files. (how much memory do you have?) I would suggest getting out of this habit as soon as possible. As others have mentioned, use seek.
