在centos 7下用cmatrix做出×××屏幕代码雨效果

1、下载cmatrix-1.2a.tar.gz文件

[[email protected] ~]# wget https://jaist.dl.sourceforge.net/project/cmatrix/cmatrix/1.2a/cmatrix-1.2a.tar.gz

2、解压缩cmatrix-1.2a.tar.gz文件

[[email protected] ~]# cd cmatrix-1.2a

[[email protected] cmatrix-1.2a]# yum install ncurses-deve

```[[email protected] cmatrix-1.2a]# ./configure && make && make install

当执行“./configure && make && make install ”命令出现如上信息时，表示没有安装gcc，gcc安装过程如下
[[email protected] cmatrix-1.2a]# yum -y install gcc
[[email protected] cmatrix-1.2a]# yum -y install gcc-c++
[[email protected] cmatrix-1.2a]# yum install make

安装完后再运行“./configure && make && make install ”命令，如下：

到此，cmatrix安装完成，任意路径，输入cmatrix运行，按q退出。效果如下

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

[[email protected] ~]# cmatrix -b -u 3 -C yellow
