Is anyone know some scripts to generate random number without repetition using bash; for example generate 10 different random numbers.

Hi,
I am currently trying to generate multiple random numbers in C for different variable:-
die1=1+(rand()%5);
die2=1+(rand()%5);
die3=1+(rand()%5);
die4=1+(rand()%5);
But I need to contrain the total of die1, die2,die3 and die4 to be 5 as well. If i insert die1+die2+die3+die4=5, i do... (6 Replies)

Hi
I have the below code
MAXCOUNT=10
count=1
echo
echo "$MAXCOUNT random numbers:"
echo "-----------------"
while # Generate 10 ($MAXCOUNT) random integers.
do
number=$ + 1 ]
"echo $number"
let "count += 1" # Increment count.
done
But aftre executing this

Hi,
I am having trouble with generating random numbers. can this be done with awk?
So I have a file that looks like this:
23 30
24 40
26 34
So column1 is start and column2 is end. I want to generate 3 random #'s between start and stop:
So the output will look like this:

Hi Can someone help me with this one?
I have string..

and i want to replace the PID number with whatever PID from

Hi everyone
I just got my hands on a T5120 running Sol10. As far as I've read, the T2 chip has a built-in hardware number generator. My question is: how can I access it to get random numbers in either C or Fortran? I'm using Sun Studio 12.4.
I am currently trying to write an... (13 Replies)

crypt::openssl::random
Random(3pm) User Contributed Perl Documentation Random(3pm)NAME
Crypt::OpenSSL::RSA - RSA encoding and decoding, using the openSSL libraries
Crypt::OpenSSL::Random - Routines for accessing the OpenSSL pseudo-random number generator
SYNOPSIS
use Crypt::OpenSSL::Random;
Crypt::OpenSSL::Random::random_seed($good_random_data);
Crypt::OpenSSL::Random::random_egd("/tmp/entropy");
Crypt::OpenSSL::Random::random_status() or
die "Unable to sufficiently seed the random number generator".
my $ten_good_random_bytes = Crypt::OpenSSL::Random::random_bytes(10);
my $ten_ok_random_bytes = Crypt::OpenSSL::Random::random_pseudo_bytes(10);
DESCRIPTION
Crypt::OpenSSL::Random provides the ability to seed and query the OpenSSL library's pseudo-random number generator
EXPORT
None by default.
Static Methods
random_bytes
This function, returns a specified number of cryptographically strong pseudo-random bytes from the PRNG. If the PRNG has not been
seeded with enough randomness to ensure an unpredictable byte sequence, then a false value is returned.
random_pseudo_bytes
This function, is similar to c<random_bytes>, but the resulting sequence of bytes are not necessarily unpredictable. They can be used
for non-cryptographic purposes and for certain purposes in cryptographic protocols, but usually not for key generation etc.
random_seed
This function seeds the PRNG with a supplied string of bytes. It returns true if the PRNG has sufficient seeding. Note: calling this
function with non-random bytes is of limited value at best!
random_egd
This function seeds the PRNG with data from the specified entropy gathering daemon. Returns the number of bytes read from the daemon
on succes, or -1 if not enough bytes were read, or if the connection to the daemon failed.
random_status
This function returns true if the PRNG has sufficient seeding.
BUGS
Because of the internal workings of OpenSSL's random library, the pseudo-random number generator (PRNG) accessed by Crypt::OpenSSL::Random
will be different than the one accessed by any other perl module. Hence, to use a module such as Crypt::OpenSSL::Random, you will need to
seed the PRNG used there from one used here. This class is still advantageous, however, as it centralizes other methods, such as
random_egd, in one place.
