Apt-get Common Commands

One, what's the Apt-get

Premium Packaging Tools (English: Advanced packaging tools, abbreviation: APT) is a package manager for Debian and its derivative distributions (e.g., Ubuntu). Apt can automatically download, configure, install binary or source-code packages, thus simplifying the process of managing software on UNIX systems, Apt-get commands typically require root access, so follow the sudo command generally.

Two, apt-get Chinese parameter

Usage:

apt-get [Options] Command apt-get [options] Install|remove pkg1 [pkg2 ...]

Apt-get [options] Source pkg1 [pkg2 ...]

Apt-get is a simple command-line interface for downloading and installing packages. The most common commands are update (update) and install (installation).

Command:

Update-Retrieve the package list again

Upgrade-Update

Install-Installs a new package

Remove-Removes the package

Autoremove-automatic removal of all unused packages

Purge-removing packages and configuration files

Source-Download Source file

BUILD-DEP-Configuring compilation dependencies for source packages

Dist-upgrade-Release Version upgrade

Dselect-upgrade-Updated according to Dselect selection

Clean-Clears the downloaded archive file

AutoClean-Clean up old downloaded archived files

Check-check to see if there is a corrupted dependency

-D Download only-do not install or unzip the archive file

-S is not actually installed. Simulation execution Commands

-Y assumes that all queries are selected, without prompting

-M if the archive cannot be located, try to continue

-U displays a list of update packages at the same time

-B Get Source package compile-V Show detailed version number

Introduction to Apt-get Working principle

As we all know, it is very convenient to use Apt-get to install the software under the Linux operating system. As long as a sudo apt-get install software name, you can easily solve the software installation, the most important thing is that he can solve the various complex dependencies, so that you do not have to do this headache, and before the advent of Apt-get, the use of dpkg or earlier. Configure;make;make install software can not imagine, installed software A, prompting you to install software B, finally installed, and prompted to install software C .... All Kinds of tangle! So apt this advanced package management tool greatly facilitates the vast number of Linux users, but also reduces the entry threshold for Linux users. Well, bits and pieces say so much nonsense, let's get back to the chase.

In order to find out the principle, I have been on the net for a long time, and finally I groped for a while, finally a little clue, whenever the execution of the software installation or update, or update the software source, APT will visit/etc/apt/ The address within the sources.list, and find the corresponding system package information in the website such as my operating system is Ubuntu, the website is Deb Http://mirrors.163.com/ubuntu/precise main restricted Universe Multiverse NetEase, then when we execute the installation of the command, he will be corresponding to the access http://mirrors.163.com/ubuntu/dists/lucid/main/binary-i386/ packages.gz, this file is a list of packages and their dependencies on the server, and is compressed with gzip. Apt-get Update uses this checklist to determine which supplemental packages are available and his content is stored in/var/lib/apt/lists, by accessing the lists to determine if the software is installed, whether it is the latest version, whether the dependencies are met, This determines the content to be updated and updated, and the installation process is primarily done by dpkg.

In general, APT is a management tool that prefers to download.
