This article mainly explains the usage of installation and management commands of software packages in Linux. The explanation in this article is simple and clear and easy to learn and understand. Please follow the editor's ideas to study and learn the usage of installation and management commands of software packages in Linux.

Apt-get

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 software packages.

The most commonly used command is update (update)

And install (installation).

Command:

Update-get the package list again

Upgrade-updates are made

Install-install the new software package

Remove-remove package

Autoremove-automatically removes all unused software packages

Purge-remove packages and configuration files

Source-download the source file

Build-dep-configure compilation dependencies for source packages

Dist-upgrade-release upgrade, see apt-get (8)

Dselect-upgrade-update as selected by dselect

Clean-clear downloaded archive files

Autoclean-clear old downloaded archive files

Check-check for corrupted dependencies

Options:

-h this help file.

-Q output to log-No progress indication

-qq does not output information, except for errors

-d download only-do not install or extract archive files

-s is not actually installed. Simulate the execution of commands

-y assume that yes is selected for all queries and no prompts are made.

-f attempts to correct the system dependency damage

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

-u also displays a list of update packages

-b compile after getting the source package

-V displays the detailed version number

-clockwise? Read this profile

-oops? Set custom configuration options, such as-o dir::cache=/tmp

Example:

The code is as follows:

Apt-cache search packagename

Search package

The code is as follows:

Apt-cache show packagename

Get information about the package, such as description, size, version, etc.

The code is as follows:

Apt-get install packagename

Installation package

The code is as follows:

Apt-get install packagename-reinstall

Reinstall the package

The code is as follows:

Apt-get-f install

Repair installation "- f =-- fix-missing"

The code is as follows:

Apt-get remove packagename

Delete package

The code is as follows:

Apt-get remove packagename-purge

Delete packages, including deleting configuration files, etc.

The code is as follows:

Apt-get update

Update sourc

The code is as follows:

Apt-get upgrade

Update installed packages

The code is as follows:

Apt-get dist-upgrade

Upgrade the system

The code is as follows:

Apt-get dselect-upgrade

Upgrade using dselect

The code is as follows:

Apt-cache depends packagename

Learn about using dependencies

The code is as follows:

Apt-cache rdepends packagename

Is to see which packages the package is dependent on

The code is as follows:

Apt-get build-dep packagename

Install the relevant compilation environment

The code is as follows:

Apt-get source packagename

Download the source code for the package

The code is as follows:

Apt-get clean

Clean up useless bags

The code is as follows:

Apt-get autoclean

Clean up useless bags

The code is as follows:

Apt-get check

Check for corrupted dependencies

Pacman

Pacman is a package manager as part of the ArchLinux distribution. It was first developed by Judd Vinet of Arch Linux. Pacman solves dependencies during installation and automatically downloads and installs all required software packages. The Pacman package manager is a highlight of Arch Linux. It combines a simple binary package format with an easy-to-use build system. Pacman makes it possible to easily manage and customize software packages, whether they come from the official Arch software library or user-created

The code is as follows:

[zhangy@BlackGhost] $pacman-h

Usage: pacman [...]

Action:

Pacman {- h-- help} / / help

Pacman {- V-- version} / / View version

Pacman {- D-- database} / / pacman Management Database options

Pacman {- Q-- query} [options] [package] / query installation package

Pacman {- R-- remove} [options] / / remove the installation package

Pacman {- S-- sync} [option] [package] / / install the installation package

Pacman {- U-- upgrade} [options] / / Update the installation package

Use 'pacman {- h-- help}' and an action to see the available options

The code is as follows:

[zhangy@BlackGhost] $pacman-D-- help

Pacman-S mysql

(2) sometimes there are multiple versions of a package (such as extra and community) in different software repositories. You can choose one to install

The code is as follows:

Pacman-S extra/mysql

(3), step by step package database and install a software package

The code is as follows:

Pacman-Sy mysql

Example 2

Delete package

(1) remove a single package and retain all of its installed dependencies

The code is as follows:

Pacman-R mysql

(2) remove the specified package and all its dependencies that have not been used by other installed packages:

The code is as follows:

Pacman-Rs mysql

Example 3

Upgrade the system

The code is as follows:

Example 4

Query package

Query available installation packages

The code is as follows:
