Hi,
From some time, we have noticed that our ascii files have started corrupting due to the presence of some random control characters (^@, ^M, ^H, ^D). The characters appear randomly on any file after the process that creates the file finishes. If we rerun the process, the files re creates... (0 Replies)
I have a directory of files that look like filename 001.ext, filename 002.ext, etc. I'd like to rename the files with unique random numbered names, so that the original filenames are stripped and the files are given a new, random number name. I'm not super new to UNIX, but I don't often use it for... (2 Replies)

Hi,
Is there any way I can shuffle the numbers randomly. I have been trying to google and I found lots of 'generator' but is it possible to find the background logic to create randomness?
Thanks, (3 Replies)

autobox::list::util
autobox::List::Util(3pm) User Contributed Perl Documentation autobox::List::Util(3pm)NAME
autobox::List::Util - bring the List::Util functions to autobox
VERSION
Version 20090629
SYNOPSIS
"autobox::List::Util" brings all of the functions from List::Util to arrays as methods.
use autobox::List::Util;
my @array = qw/ foo bar baz /;
print @array->first(sub { /ar/ }), "
"; # "bar"
print [5, 6, 3, 4]->max, "
"; # 6
print @array->maxstr, "
"; # baz
print [5, 6, 3, 4]->min, "
"; # 3
print @array->minstr, "
"; # foo
print [1 .. 10]->shuffle, "
"; #1 to 10 randomly shuffled
print [1 .. 10]->sum, "
"; # 55
print [1 .. 10]->reduce( sub { $a + $b } ), "
"; # 55
METHODS
first(coderef)
This method behaves nearly the same as the first function from List::Util, but it takes a coderef not a block because methods can't use
prototypes.
reduce(coderef)
This method behaves nearly the same as the reduce function from List::Util, but it takes a coderef not a block for the same reason. It
also has a bug (see BUGS)
shuffle
If called in scalar context it returns a reference to an array instead of a list. This allows shuffle to be chained with other calls.
max, maxstr, min, minstr, sum
These methods behave exactly the same as their List::Util counterparts.
AUTHOR

BUGS
The reduce method works with $main::a and $main::b, not your current package's $a and $b, so you need to say
print @array->reduce( sub { $main::a + $main::b } ), "
";
if you are not in the main package. Reduce uses $_, so it doesn't suffer from this problem.
