2.Ubuntu使用apt-get命令遇到的问题

2.安装软件

sudo apt-get install <软件包名> 软件包名一般为软件名，也可使用sudo apt-cache search <关键字> 模糊搜索。

若提示“不能理解命令行选项g来自get与其他选项的搭配”，可以尝试将apt -get 替换为 apt

3.查看apt帮助信息apt-get --help

# 删除软件及其配置文件
apt-get --purge remove <package>
# 删除没用的依赖包
apt-get autoremove <package>
# 此时dpkg的列表中有“rc”状态的软件包，可以执行如下命令做最后清理：
dpkg -l | grep ^rc | awk '{print $2}' | sudo xargs dpkg -P
