基本概念
screenFetch：一个“命令行信息截图工具”。它可以在终端上显示系统信息，并进行桌面截图。它能生成漂亮的文本的系统信息和ASCII艺术的发行版LOGO，然后显示在截屏图片中。
它会自动检测你的发行版并显示其ASCII版本的LOGO，在其右侧显示系统信息。可以通过选项来指定是否显示LOGO、指定颜色，进行截图，甚至可以自定义截图的命令。screenFectch非常容易添加和扩展。
screenFetch将显示以下系统信息：
- 当前登录用户
- 操作系统版本
- 内核版本
- 总计运行时间
- 已安装包数量
- 当前shell详情
- 当前屏幕分辨率
- 当前桌面环境
- 当前窗口管理器（文件管理器）
- 总计及空闲磁盘使用百分比
- CPU详情，如处理器速度、类型
- 总计及当前内存使用量
