I have attempted to create an array consisting of two items: #0 and #1.
I am able to print the two items corrctly:
However, when I try to run a for loop to print both objects:
I get:
If there are two objects, why is the output on four lines? How do I loop on two lines?
We just purchased a MOD30 disk array strage system.
We have 15 drives and 2 hot spares.
We're running a database app with 8 data sets.
I'm trying to get the best i/o speed out of my disk configuration.
Right now I have 3 raid5 arrays setup. This seems to offer the same performance as having the... (1 Reply)
When setting a variable, how would I go about making each result a new line?
A very simple example would be:
theFolders=`(ls -l /)`
echo $theFolders
This gives me all the folders as one variable and I need to be able to use each as its own variable. I'm sure I have to make this into an... (2 Replies)

These are the steps in my Shell script.

I am trying to assign indexes to an associative array in a for loop but I have to use an eval command to make it work, this doesn't seem correct I don't have to do this with regular arrays

prima::tie
Prima::Tie(3) User Contributed Perl Documentation Prima::Tie(3)NAME
Prima::Tie - tie widget properties to scalars or arrays.
DESCRIPTION
Prima::Tie contains two abstract classes, "Prima::Tie::Array" and "Prima::Tie::Scalar", which tie an array or a scalar to a widget's
arbitrary array or scalar property. Also, it contains classes "Prima::Tie::items", "Prima::Tie::text", and "Prima::Tie::value", which tie
a variable to a widget's items, text, and value property respectively.
SYNOPSIS
use Prima::Tie;
tie @items, 'Prima::Tie::items', $widget;
tie @some_property, 'Prima::Tie::Array', $widget, 'some_property';
tie $text, 'Prima::Tie::text', $widget;
tie $some_property, 'Prima::Tie::Scalar', $widget, 'some_property';
USAGE
These classes provide immediate access to a widget's array and scalar property, in particular to popular properties as items and text. It
is considerably simpler to say
splice(@items,3,1,'new item');
than to say
my @i = @{$widget->items};
splice(@i,3,1,'new item');
$widget->items(@i);
You can work directly with the text or items rather than at a remove. Furthermore, if the only reason you keep an object around after
creation is to access its text or items, you no no longer need to do so:
tie @some_array, 'Prima::Tie::items', Prima::ListBox->create(@args);
As opposed to:
my $widget = Prima::ListBox->create(@args);
tie @some_array, 'Prima::Tie::items', $widget;
"Prima::Tie::items" requires "::items" property to be available on the widget. Also, it takes advantage of additional "get_items",
"add_items", and the like if available.
Prima::Tie::items
The class is applicable to "Prima::ListViewer", "Prima::ListBox", "Prima::Header", and their descendants, and in limited fashion to
"Prima::OutlineViewer" and its descendants "Prima::StringOutline" and "Prima::Outline".
Prima::Tie::text
The class is applicable to any widget.
Prima::Tie::value
The class is applicable to "Prima::GroupBox", "Prima::ColorDialog", "Prima::SpinEdit", "Prima::Gauge", "Prima::Slider",
"Prima::CircularSlider", and "Prima::ScrollBar".
