+apk
+===
+
+Alpine Linux 下的包管理工具
+
+## 使用实例
+
+```shell
+apk install xxx
+apk search xxx # 支持正则
+apk info xxx # 查看包的详细信息
+apk show # list local package
+# 卸载并删除 包
+apk del openssh openntp vim
+```
+
+### 升级
+
+upgrade命令升级系统已安装的所以软件包（一般包括内核），当然也可指定仅升级部分软件包（通过-u或–upgrade选择指定）。
+
+```shell
+apk update # 更新最新本地镜像源
+apk upgrade # 升级软件
+apk add --upgrade busybox # 指定升级部分软件包
+```
+
+### 搜索
+
+```shell
+apk search # 查找所以可用软件包
+apk search -v # 查找所以可用软件包及其描述内容
+apk search -v 'acf*' # 通过软件包名称查找软件包
+apk search -v -d 'docker' # 通过描述文件查找特定的软件包
+```
+
+### 查看包信息
+
+info命令用于显示软件包的信息。
+
+```shell
+apk info # 列出所有已安装的软件包
+apk info -a zlib # 显示完整的软件包信息
+apk info --who-owns /sbin/lbu # 显示指定文件属于的包
+```
+
+## 笔记
+
+还是蛮喜欢 alpine 的，简单纯粹
+
+```shell
+apk add iproute2 # ss vs netstat
+ss -ptl
+apk add drill # drill vs nslookup&dig
+
+crond # 开启 cron 服务
+crontab -l -e
+
