I'm not quite sure what you are asking, but I'll answer some questions that you might have been asking :)

Removing first and last line of a file: 

use strict;
open FILE, "</path/to/inputfile" or die "Blerch: $!\n";
# Set $/ to whatever your line terminating char is in inputfile
my @lines=<FILE>;
shift @lines;
pop @lines;
# @lines now contains the file contents without the first and last lin
+es.

Removing leading # from a line: 

$line=~s/^#//;

Inserting a leading # in a line: 

$line=~s/^(.)/#$1/;

Note that the above code is untested however, and might do all kinds of funny stuff, not excluding actually working as intended.
