This article mainly introduces the differences between rpm format and deb format, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand it.

The difference is: RPM is the package management system of Linux Distribution, but also refers to the rpm package itself, RPM is used for the management of rpm packages; for Debian-based systems using deb format packages, there are package conversion tools to convert rpm to deb and other files.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

1. About rpm and deb

RPM (Red Hat Package Manager) is a Red hat-based Linux Distribution package management system, which also refers to the rpm package itself. RPM is used for the management of rpm packages (such as installation, uninstallation, upgrade, etc.). RPM-based distributions like Mandrake and SuSE usually have their own specific rpm packages, which may not work properly if mixed installation, while rpm packages issued by third parties can generally be installed on RPM-based systems.

For packages based on Debian using deb format, there are package conversion tools to convert rpm to deb and other files (Alien Package Converter). Dpkg can be used for installation and upgrade, but it can not easily deal with package dependencies. Dselect and apt-get are more convenient. Ubunut is a variant of debian, and its software appears in the form of deb packages or source files.

Format and use of 2.deb software package

(1) the .deb package command follows the following convention:

Soft_ver-rev_arch.deb, such as: pptview_8.0-5_i386.deb in the name is pptview, version number 8.0, the architecture is i386 platform.

(2) dpkg command

Sometimes, when you install a package using "dpkg", you will be prompted that the package depends on other packages. At this point, you install other software packages until the dependencies are met. Or install multiple software packages at the same time

Dpkg-I aaa.deb bbb.deb ccc.deb

3. Ubuntu's apt- command can automatically complete software dependencies, mostly using apt-get. In fact, there are other uses that can be explored, such as the following

Root@huxiping:~# apt-

Apt-cache apt-config apt-ftparchive apt-key

Apt-cdrom apt-extracttemplates apt-get apt-sortpkgs

Root@huxiping:~# apt-

If a software dependency is too complex and it is not a wise choice to use "dpkg" to install it, you need to use the APT package management system. APT can automatically check dependencies, obtain the relevant software package by default, and automatically install and configure it. In fact, in most cases, we recommend that you use the APT package to manage the system.

The APT system requires a software information database and at least one software repository with a large number of deb packages, which we call the "source". The "source" can be a network server, install CD or a local software repository. You need to modify

The / etc/apt/sources.list file enables the APT system to connect to the Source.
