apt与apt-get命令

apt-get是Debian及Ubuntu这类Linux发行版中最常用的软件安装命令,前几天又发现一个很相似的命令apt,也可以用于安装软件。去网上搜索了下这两个命令,整理如下。

apt-get是一个传统的包管理程序,而apt似乎是Ubuntu Trusty之后才引入的一个新程序。具体讨论可参考下面这个链接:

What is the difference between apt and apt-get?

重点内容摘录如下:

They are very similar command line tools available in Trusty. Apt-get and apt-cache’s most commonly used commands are available in apt.

apt-get may be considered as lower-level and “back-end”, and support other APT-based tools. apt is designed for end-users (human) and its output may be changed between versions.

The big news for this version is that we included a new apt binary that combines the most commonly used commands from apt-get and apt-cache. The commands are the same as their apt-get/apt-cache counterparts but with slightly different configuration options.

一言以蔽之,apt可以视为是对apt-getapt-cache中常用命令的二次打包封装,一般来说,可以直接使用apt来替代apt-getapt-cache,它们之间并没有什么大的差别,而apt使用起来会更方便。

apt支持以下命令操作:

命令 作用
list 列出已安装的软件包
search 在源索引文件中搜索软件包
show 列出特定软件包的详细信息
install 安装软件包
remove 移除软件包
edit-sources 编辑源列表
update 同步源索引文件
