Hi,
I'm in the midst of writing a UNIX script that sftp's files to an external host and am stuck with a problem. The problem is that the files created on my server as a order number that correlates to a sequence of directories on the remote host which is where the file should be ftp'ed.

moose::autobox::array
Moose::Autobox::Array(3pm) User Contributed Perl Documentation Moose::Autobox::Array(3pm)NAME
Moose::Autobox::Array - the Array role
SYNOPOSIS
use Moose::Autobox;
[ 1..5 ]->isa('ARRAY'); # true
[ a..z ]->does('Moose::Autobox::Array'); # true
[ 0..2 ]->does('Moose::Autobox::List'); # true
print "Squares: " . [ 1 .. 10 ]->map(sub { $_ * $_ })->join(', ');
print [ 1, 'number' ]->sprintf('%d is the loneliest %s');
print ([ 1 .. 5 ]->any == 3) ? 'true' : 'false'; # prints 'true'
DESCRIPTION
This is a role to describe operations on the Array type.
METHODS
pop
push ($value)
shift
unshift ($value)
delete ($index)
sprintf ($format_string)
slice (@indices)
flatten
flatten_deep ($depth)
first
last
Indexed implementation
at ($index)
put ($index, $value)
exists ($index)
keys
values
kv
each
each_key
each_value
each_n_values ($n, $callback)
List implementation
head
tail
join (?$seperator)
length
map (&block)
grep (&block)
Note that, in both the above, $_ is in scope within the code block, as well as being passed as $_[0]. As per CORE::map and CORE::grep,
$_ is an alias to the list value, so can be used to to modify the list, viz:
use Moose::Autobox;
my $foo = [1, 2, 3];
$foo->map( sub {$_++} );
print $foo->dump;
yields
$VAR1 = [
2,
3,
4
];
reverse
sort (?&block)
Junctions
all
any
none
one
meta
print
say
