使用 apt-get 安装 Linux 软件包
在这一步中，你将学习如何使用 apt-get 命令安装 Linux 软件包。apt-get 是一个强大的工具，用于管理基于 Ubuntu 的 Linux 发行版上的软件包。
首先，让我们更新软件包列表，以确保我们拥有关于可用软件包的最新信息：
sudo apt-get update
示例输出：
Hit:1 http://archive.ubuntu.com/ubuntu jammy InRelease
Get:2 http://archive.ubuntu.com/ubuntu jammy-updates InRelease [114 kB]
Get:3 http://archive.ubuntu.com/ubuntu jammy-security InRelease [110 kB]
Get:4 http://archive.ubuntu.com/ubuntu jammy-backports InRelease [99.8 kB]
Fetched 324 kB in 1s (324 kB/s)

接下来，我们使用 apt-get install 安装一个软件包。我们将安装 tree 软件包，这是一个命令行工具，用于以树状格式显示目录结构：
sudo apt update
sudo apt-get install -y tree
示例输出：
