Centos 使用 neofetch 替换原生 motd
介绍 neofetch
Neofetch 是一个轻量级的命令行工具，它可以显示当前操作系统的信息和系统配置的各种详细信息。它在终端中以 ASCII 艺术的形式显示了许多系统信息，例如：
- 操作系统名称和版本
- 内核版本
CPU型号和速度GPU型号和驱动程序- 系统主机名
- 系统语言
- 内存使用情况
- 硬盘使用情况
它还支持定制化，您可以在配置文件中更改 ASCII 艺术，更改颜色主题，添加自定义命令等。
由于它的轻量级和易于使用，Neofetch 在 Linux 用户社区中非常流行，并成为了许多 Linux 用户的常用工具之一。
