apt-get command cheat sheet for Debian Linux

apt-get is the command-line tool for handling packages for Debian Linux which is use to:

  • Install/manage individual packages
  • Upgrade packages
  • Apply security patch(s)
  • Keep Debian system up to date
  • Download source .deb files
  • Front-end to many GUI and other utilities

Here is quick cheat sheet you will find handy while using apt-get at shell prompt:

SyntaxDescriptionExample(s)
apt-get install {package}Install the new package. If package is installed then try to upgrade to latest versionapt-get install zip
apt-get install lsof samba mysql-client
apt-get remove {package}Remove/Delete an installed package except configuration filesapt-get remove zip
apt-get --purge remove {package}Remove/Delete everything including configuration filesapt-get --purge remove mysql-server
apt-get update
apt-get upgrade
Resynchronize the package index files and Upgrade the Debian Linux system including security update (Internet access required)apt-get update
apt-get upgrade
apt-get update
apt-get dist-upgrade
Usually use to upgrade to Debian distribution. For example Woody to Sarge upgrade. 'dist-upgrade' in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary.apt-get update
apt-get dist-upgrade

{package} - Replace with actual package name

 

 

安装或升级系统分下面几个步骤。

第一步,获得最近的软件包的列表;列表中包含一些包的信息,比如这个包是否更新过。

第二步,如果这个包没有发布更新,就不管它;

            如果发布了更新,就把包下载到电脑上,并安装。

 

apt-get update对应的就是第一步。

apt-get upgrade 与apt-get dist-upgrade对应的是第二步。

 

由于包与包之间存在各种依赖关系。upgrade只是简单的更新包,不管这些依赖,它不和添加包,或是删除包。而dist-upgrade可以根据依赖关系的变化,添加包,删除包。

 

一般在运行upgrade或dist-upgrade之间,要运行update.
