aptitude 与 apt-get 一样，是 Debian 及其衍生系统中功能极其强大的包管理工具。与 apt-get 不同的是，aptitude 在处理依赖问题上更佳一些。举例来说，aptitude 在删除一个包时，会同时删除本身所依赖的包。这样，系统中不会残留无用的包，整个系统更为干净。
以下是笔者总结的一些常用 aptitude 命令，仅供参考。
命令 作用
aptitude update 更新可用的包列表
aptitude upgrade 升级可用的包
aptitude dist-upgrade 将系统升级到新的发行版
aptitude install pkgname 安装包
aptitude remove pkgname 删除包
aptitude purge pkgname 删除包及其配置文件
aptitude search string 搜索包
aptitude show pkgname 显示包的详细信息
aptitude clean 删除下载的包文件
aptitude autoclean 仅删除过期的包文件
有的问题 apt-get 解决不了，必须使用 aptitude 解决，有的问题，用 aptitude 解决不了，必须使用apt-get.
aptitude 解决得更好的地方： install, remove, reinstall（apt-get无此功能）, show（apt-get无此功能）, search（apt-get无此功能）, hold（apt-get无此功能）, unhold（apt-get无此功能）,
apt-get 解决得更好的地方： source（aptitude无此功能）, build-dep （低版本的aptitude没有build-dep功能）
apt-get 跟 aptitude 没什么区别的地方：update, upgrade (apt-get upgrade=aptitude safe-upgrade, apt-get dist-upgrade=aptitude full-upgrgade)
