25个对于软件包管理的APT-GET和APT-CACHE的有用的基本命令

这篇文章解释你可以学到如何快速 安装删除更新和使用命令行 易于得到apt-缓存命令 搜索软件包。 本文提供了一些有用的命令,这将帮助你处理 的Debian / Ubuntu的软件包管理为基础的系统。

APT-GET和APT-CACHE命令

什么是apt-get?
apt-get工具是一个强大的和免费的软件包管理命令行程序,用于与 Ubuntu的APT( 高级包装工具 )库执行安装新的软件包,删除现有的软件包,现有的软件包,甚至升级工作用于升级整个操作系统。
什么是apt缓存?
apt-cache命令行工具用于搜索容易软件包缓存。 简单地说,这个工具是用来搜索软件包,收集包的信息,并用于搜索哪些可用的软件包已准备好安装在基于 DebianUbuntu系统。
APT-CACHE - 5有用的基本命令

1.如何列出所有可用的软件包?

要列出所有可用的软件包,请键入以下命令。
$ apt-cache pkgnames
esseract-ocr-epo
pipenightdreams
mumudvb
tbb-examples
libsvm-java
libmrpt-hmtslam0.9
libboost-timer1.50-dev
kcm-touchpad
g++-4.5-multilib
...

2.如何找出软件包名称和描述?

要找出包的名称,并在安装前说明,请使用“ 搜索 ”的标志。 使用“ 搜索从apt-cache将显示简短的描述匹配的包的列表。 比方说,你想找出包' 的vsftpd“的说明,然后命令会。
$ apt-cache search vsftpd
vsftpd - lightweight, efficient FTP server written for security
ccze - A robust, modular log coloriser
ftpd - File Transfer Protocol (FTP) server

找到并列出下以 'vsftpd的 “全包,可以使用下面的命令。
$ apt-cache pkgnames vsftpd
vsttpd

3.如何检查包裹信息?

例如,如果您想检查包的信息以及简短描述说明(版本号,校验和,大小,安装大小,类别等)。使用“ 显示 ”,如下图所示子命令。
