How could i use perl to create a random series of numbers say from 1 to 10 with no repetitions and all the numbers must also be used.. rand function gives only one number as the output, and also even if i use it repeatedly with different seeds how can i prevent repetition of numbers..??
   

Don't use rand. Just create an array of the numbers and use the List::Util module and the shuffle function:

Code:

use List::Util qw/shuffle/;   my @numbers = (1..10); @numbers = shuffle(@numbers); print "@numbers";
