导读 | dpkg 意即 Debian 包管理器(Debian PacKaGe manager)。dpkg 是一个可以安装、构建、删除及管理 Debian 软件包的命令行工具。dpkg 将 Aptitude(首选而对用户更友好)作为执行所有操作的前端界面。 |
其它的一些工具如 dpkg-deb 和 dpkg-query 等也使用 dpkg 作为执行某些操作的前端。现在大多数系统管理员使用 Apt、Apt-Get 及 Aptitude 等工具,不用费心就可以轻松地管理软件。
尽管如此,必要的时候还是需要用 dpkg 来安装某些软件。其它的一些在 Linux 系统上广泛使用的包管理工具还有 yum、dnf、apt-get、rpm、Zypper、pacman、urpmi 等等。
下面是 dpkg 常见命令的语法及 dpkg 相关文件的位置,如果想深入了解,这些对你肯定大有益处。### dpkg 命令的语法
$ dpkg -[command] [.deb package name]
$ dpkg -[command] [package name]
### dpkg 相关文件的位置
$ /var/lib/dpkg
### 这个文件包含了被 dpkg 命令(install、remove 等)所修改的包的信息
$ /var/lib/dpkg/status
### 这个文件包含了可用包的列表
$ /var/lib/dpkg/status
在基于 Debian 的系统里,比如 Debian、Mint、Ubuntu 和 elementryOS,用以下命令来安装/升级 .deb 软件包。这里我要用 atom-amd64.deb
文件安装 Atom。要是已经安装了 Atom,就会升级它。要么就会安装一个新的 Atom。### 安装或升级 dpkg 软件包
$ sudo dpkg -i atom-amd64.deb

在基于 Debian 的系统里,用下列命令从目录中逐个安装软件。这会安装 /opt/software
目录下的所有以 .deb 为后缀的软件。$ sudo dpkg -iR /opt/software
