linux命令画圣诞树图片,分享|Linux/Unix 桌面趣事：终端上的圣诞树

给你的Linux或Unix控制台创造一棵圣诞树玩玩吧。在此之前，需要先安装一个Perl模块，命名为Acme::POE::Tree。这是一棵很喜庆的圣诞树，我已经在Linux、OSX和类Unix系统上验证过了。

安装 Acme::POE::Tree

安装perl模块最简单的办法就是使用CPAN(Perl综合典藏网(Comprehensive Perl Archive Network))。打开终端，把下面的指令敲进去便可安装Acme::POE::Tree。

### 以root身份运行 ###

perl -MCPAN -e 'install Acme::POE::Tree'

示例输出：

在Shell中显示圣诞树

只需要在终端上运行以下命令：

perl -MAcme::POE::Tree -e 'Acme::POE::Tree->new()->run()'

示例输出

树的定制

以下是我的脚本文件tree.pl的内容：

#!/usr/bin/perl

use Acme::POE::Tree;

my $tree = Acme::POE::Tree->new(

{

star_delay => 1.5, # shimmer star every 1.5 sec

light_delay => 2, # twinkle lights every 2 sec

run_for => 10, # automatically exit after 10 sec

}

);

$tree->run();

这样就可以通过修改stardelay、runfor和light_delay参数的值来自定义你的树了。一棵好玩的终端圣诞树就此诞生。
