Linux/Unix 桌面盛典:模仿 “黑客帝国” 界面!
|
||
======
|
||
|
||
《黑客帝国》是 1999 年,由 Wachowki 兄弟编导的科幻动作片。这部电影的荧屏里有无尽的绿色字符降落。数字雨模拟着《黑客帝国》中的虚拟现实活动。现在,Linux 和 Unix 终端上,你也可以通过 CMatrix 模仿出矩阵数字雨。

||
| `b` | 随机字符加粗 |
|
||
| `B` | 全部字符加粗 |
|
||
| `n` | 关闭字符加粗 |
|
||
| `0`-`9` | 调整更新时间 |
|
||
| `!` `@` `#` `$` `%` `^` `&` `)` | 改变对应的矩阵颜色: `!` – 红、`@` – 绿、`#` – 黄、`$` – 蓝、`%` – 洋红、`^` – 青、 `&` – 白、 `)` – 黑。 |

||
- `-b`: 开启字符加粗
|
||
- `-B`: 所有字符加粗(优先于 -b 选项)
|
||
- `-f`: 强制开启 Linux $TERM 模式
|
||
- `-l`: Linux 模式(使用 matrix 控制台字体)
|
||
- `-o`: 启用旧式滚动
|
||
- `-h`: 输出使用说明并退出
|
||
- `-n`: 关闭字符加粗 (优先于 -b and -B,默认)
|
||
- `-s`: “屏保”模式, 第一次按键时退出
|
||
- `-x`: X 窗口模式,如果你使用的时 mtx.pcf 终端
