Full Discussion: Generating a Random String of 'n' length

This is a linux example for reasonably random dates using /dev/random:
(/dev/urandom gives better random numbers but is overkill for learning)

Code:
date -d `echo @ $(od --read-bytes=4 --address-radix=n --format=u4 /dev/random)| awk '{print $1$2}'`

You need to specify a little more background - what UNIX, what shell? In general it is possible especially using perl and awk

crypt::random::source::factory

Crypt::Random::Source::Factory(3pm)			User Contributed Perl Documentation		       Crypt::Random::Source::Factory(3pm)

NAME

       Crypt::Random::Source::Factory - Load and instantiate sources of random data

SYNOPSIS

	   use Crypt::Random::Source::Factory;

	   my $f = Crypt::Random::Source::Factory->new;

	   my $strong = $f->get_strong;

	   my $weak = $f->get_weak;

	   my $any = $f->get;

DESCRIPTION

       This class implements a loading and instantiation factory for Crypt::Random::Source objects.

       If $ENV{CRYPT_RANDOM_NOT_PLUGGABLE} is set then only a preset list of sources will be tried. Otherwise Module::Find will be used to locate
       any installed sources, and use the first available one.

METHODS

   get %args
       Instantiate any random source, passing %args to the constructor.

       The "type" argument can be "weak", "strong" or "any".

   get_weak %args
   get_strong %args
       Instantiate a new weak or strong random source.
