.... and wrapped it in CODE tags, the edited it to look how you would like.
Wrapping in CODE tags will respect the spaces which is important for indenting or fixed-width data, or in your case a text-based diagram. I've tried, but I'm not quite sure what you want to show.
A short tutorial is included below. The look/feel of the forum has changed, as have the buttons, but method 1 still works just fine.
A program named /usr/bin/aa.sh, two parameters: 11, 22. after start it, the row in `ps -ef` is almost like the following:

Yesterday my customer told me to expect a vcs upgrade to happen in the future. He also plans to stop using HDS and move to EMC.
Am thinking how to migrate to sun cluster setup instead.

SDL Manual
"SDL::Tutorial" are incomplete and old. A new book has been started to provide a complete tutorial for SDL. See <http://bit.ly/hvxc9V>.
SDL BASICS
SDL, the Simple DirectMedia Layer, is a cross-platform multimedia library. These are the Perl 5 bindings. You can find out more about SDL
at <http://www.libsdl.org/>. You can find out more about SDL perl at <http://sdl.perl.org>.
Creating an SDL application with Perl is easy. You have to know a few basics, though. Here's how to get up and running as quickly as
possible.
Surfaces
All graphics in SDL live on a surface. You'll need at least one. That's what SDLx::App provides.
Of course, before you can get a surface, you need to initialize your video mode. SDL gives you several options, including whether to run
in a window or take over the full screen, the size of the window, the bit depth of your colors, and whether to use hardware acceleration.
For now, we'll build something really simple.
Initialization
SDLx::App makes it easy to initialize video and create a surface. Here's how to ask for a windowed surface with 640x480x16 resolution:
use SDLx::App;
my $app = SDLx::App->new(
width => 640,
height => 480,
depth => 16,
);
You can get more creative, especially if you use the "title" and "icon" attributes in a windowed application. Here's how to set the window
title of the application to "My SDL Program":
use SDLx::App;
my $app = SDLx::App->new(
height => 640,
width => 480,
depth => 16,
title => 'My SDL Program',
);
Setting an icon is a little more involved -- you have to load an image onto a surface. That's a bit more complicated, but see the "name"
parameter to "SDL::Surface-"new()> if you want to skip ahead.
Working With The App
Since $app from the code above is just an SDL surface with some extra sugar, it behaves much like SDL::Surface. In particular, the all-
important "blit" and "update" methods work. You'll need to create SDL::Rect objects representing sources of graphics to draw onto the
$app's surface, "blit" them there, then "update" the $app.
Note: "blitting" is copying a chunk of memory from one place to another.
That, however, is another tutorial.
