Hi

I have been trying to get to grips with this and am hoping to replace the random generation of the ranges (which I presume is this bit: 

my @ranges = map{
   my $a = rand( 900 );
   [ $a, $a + rand( 1000 - $a ) ]
} 1 .. 7;

with a way of reading in some values from a command's output, specifically, the first sector and last sector values from a disk partition table (which I can read in from a temporary file if needbe): 

*                          First     Sector    Last
* Partition  Tag  Flags    Sector     Count    Sector  Mount Directory

I am finding this to be pretty tough as I am a novice. Any help or suggestions appreciated.
