today=${1:-${today}}
but both gives the same value for $today
user:/export/home/user>today=`date '+%y%m%d'`
user:/export/home/user>echo $today

I just found the website coolerbooks.com a couple weeks ago. It was a site that had loads of free ebooks for download.
But now it seems to have been hijacked by some Microsoft search thing.
There was an article last year claiming it teamed with Google (the anti-Microsoft!) to offer the... (2 Replies)

8. SuSE
I posted three specific queries relating to Suse earlier today but they've disappeared.
I originally incorrectly posted them in the Unix begiiners forum, edited them out from there and re-posted under Linux.
I'm guessing they've been mistaken for some kind of flood post as they have the same... (3 Replies)

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
