吨Neofetch 命令类似于用一个工具编写的实用程序 bash 贝壳。 neofetch 的主要目的是在屏幕截图中向其他用户显示您正在使用的操作系统或 Linux 发行版，包括主题、图标、硬件配置等。 此命令在图像旁边显示有关您的系统的信息、您的操作系统徽标和其他信息。 Neofetch 5.0.0 版本已经发布。 让我们看看如何在 Linux 或类 Unix 系统上安装最新版本的 neofetch 以获取系统信息。

neofetch – 很棒的系统信息 bash 适用于 Linux、MacOS、*BSD 和类 Unix 系统的脚本

自然，你需要 bash shell 安装在您的系统上。 从项目主页：

Neofetch 是一个命令行系统信息工具 bash 3.2+。 Neofetch 以美观且视觉上令人愉悦的方式显示有关您的操作系统、软件和硬件的信息。 Neofetch 的总体目的是用于您系统的屏幕截图。 Neofetch 显示其他人想看到的信息。 还有其他工具可用于正确的系统统计/诊断。 Neofetch 支持近 150 种不同的操作系统。 从 Linux 到 Windows，一直到更晦涩的操作系统，如 Minix、AIX 和 Haiku。

如何在 Linux 或类 Unix 系统上安装 neofetch

键入以下 wget 命令以获取最新的 tar 球：
