Here are two more solutions, both using different perl modules.
Observations: the shuffle would not return any duplicates, the Data/Random would not return duplicates until the result is quite long -- longer than the source strings (this is partly a guess and partly observation), the Data/Random/String can return duplicates as seen below.
My problem is as follow and i hope you can help:
I currently have this function:
stored_word()
{
number=$RANDOM
let "number %= 21"
case $number in
0 ) echo "energy" ;; 1 ) echo "touch" ;;
2 ) echo "climbing" ;; 3 ) echo "declare" ;;
4 ) echo "marry" ;; 5 ) echo "relax" ... (8 Replies)

Need to use dd to generate a large file from a sample file of random data. This is because I don't have /dev/urandom.
I create a named pipe then:
dd if=mynamed.fifo do=myfile.fifo bs=1024 count=1024

Sometimes it is handy to protect long scripts in C++.
The following syntax works fine for simple commands:
#define SHELLSCRIPT1 "\
#/bin/bash \n\
echo \"hello\" \n\
"
int main ()
{
cout <<system(SHELLSCRIPT1);
return 0;
}
Unfortunately for there are problems for:

crypt::random::source::base
Crypt::Random::Source::Base(3pm) User Contributed Perl Documentation Crypt::Random::Source::Base(3pm)NAME
Crypt::Random::Source::Base - Abstract base class for Crypt::Random::Source classes
SYNOPSIS
use Moose;
extends qw(Crypt::Random::Source::Base);
DESCRIPTION
This is an abstract base class.
In the future it will be a role.
METHODS
get $n, %args
Gets $n random bytes and returns them as a string.
This method may produce fatal errors if the source was unable to provide enough data.
read $buf, $n, [ $off ]
This method is cannibalized from IO::Scalar. It provides an IO::Handle work-alike.
Note that subclasses override this to operate on a real handle directly if available.
seed @stuff
On supporting sources this method will add @stuff, whatever it may be, to the random seed.
Some sources may not support this, so be careful.
available
This is a class method, such that when it returns true calling "new" without arguments on the class should provide a working source of
random data.
This is use by Crypt::Random::Source::Factory.
rank
This is a class method, with some futz value for a ranking, to help known good sources be tried before known bad (slower, less available)
sources.
get_data %Params
Provided for compatibility with Crypt::Random
