aaaa
bbbb
cccc
eeee
and I would like to print or display it like this:
eeee
cccc
bbbb
aaaa

It is very simple to remove a hyphen from a word anywhere in that word using a simple sed command (sed -i 's/-//g' filename), but I am not able to figure out how to do this:
For example,
apple
-orange
tree
pipe-
banana-shake
dupe-
What my output should look like:

layout::manager::grid
Layout::Manager::Grid(3pm) User Contributed Perl Documentation Layout::Manager::Grid(3pm)NAME
Layout::Manager::Grid - Simple grid-based layout manager.
DESCRIPTION
Layout::Manager::Grid is a layout manager places components into evenly divided cells.
When you instantiate a Grid manager, you must supply it with a count of how many rows and columns it will have. For example, a Grid with 1
column and 2 rows would look like:
+--------------------------------+
| |
| component 1 |
| |
+--------------------------------+
| |
| component 2 |
| |
+--------------------------------+
The container is divided into as many <rows> * <columns> cells, with each taking up an equal amount of space. A grid with 3 columns and 2
rows would create 6 cells that consume 33% of the width and 50% of the height.
Components are placed by specifying the cell they reside in via the row and column number.
$container->add_component($comp, { row => 0, column => 3 });
$container->add_component($comp, { row => 0, column => 2, height => 2 });
Optionally, you may choose to override the default "width" or "height" of 1. Setting it to a something else will cause the component to
consume that many rows or columns worth of space.
Grid is similar to Java's GridLayout <http://java.sun.com/docs/books/tutorial/uiswing/layout/grid.html>.
SYNOPSIS
$cont->add_component($comp1, { row => 0, column => 1 });
$cont->add_component($comp2, { row => 0, column => 2 });
my $lm = Layout::Manager::Grid->new(rows => 1, columns => 2);
$lm->do_layout($con);
DYNAMIC SIZING
If the container that the Grid is manging does not have one or both of it's dimensions set, Grid will compute the appropriate sizes. The
simple way for me to avoid writing a long explanation is to say it works similar to HTML tables. Rows will become as big as their biggest
consituent, as will columns. It is common to add a Grid-managed component to a scene with only one of it's dimensions set.
ATTRIBUTES
columns
The number of columns in this Grid.
rows
The number of rows in this Grid.
METHODS
do_layout
Size and position the components in this layout.
