在centos 7下用cmatrix做出《HK帝国》屏幕代码雨效果

1，下载CMATRIX-1.2a.tar.gz文件

[root@localhost ~]# wget  --2018-07-17 15:06:03-- https://jaist.dl.sourceforge.net/project/cmatrix/cmatrix/1.2a/cmatrix-1.2a.tar.gz Resolving jaist.dl.sourceforge.net (jaist.dl.sourceforge.net)... 150.65.7.130, 2001:df0:2ed:feed::feed Connecting to jaist.dl.sourceforge.net (jaist.dl.sourceforge.net)|150.65.7.130|:443... connected.

[root@localhost cmatrix-1.2a]# cmatrix cmatrix常用命令如下: -a :异步滚动（默认）
-b :随机粗体
-B :全部粗体
-o :使用旧风格滚动
-x :X window 模式
-V :显示版本信息
-u :刷新频率，0-9，也就是滚动的快慢（值越小越快）
-C :显示的颜色，支持green(默认),red,blue,white,yellow,cyan,magenta and black

[root@localhost ~]# cmatrix -b -u 3 -C yellow
