The comparison between Ubuntu package management and Redhat

About package Management thanks to this article for an introduction to the package management approach that inspired Ubuntu (Apt-get, dpkg, aptitude)

Especially for administrators who go from Rhel to Ubuntu, they can get started quickly.

Excerpt:

Apt-cache Search Package #搜索包 (equivalent to Yum list | grep pkg) Apt-cache Show package #显示包的相关信息, such as description, size, version Apt-cache SHOWPG package #显示包的相关信息, such as reverse Depends (reverse dependency), dependency, etc. a Pt-get Install package #安装包apt-get Reinstall package #重新安装包apt-get-f Install package #强制安装apt-get Remove PAC Kage #删除包 (just delete data and executables, do not delete configuration files) apt-get remove--purge package #删除包, including deleting profiles apt-get autoremove--purge packag e #删除包及其依赖的软件包 + config file, etc. apt-get update #更新源apt-get upgrade #更新已安装的包apt-get dist-upgrade #升级系统apt-get DSE Lect-upgrade #使用 Dselect Upgrade Apt-cache depends package #了解使用依赖apt-cache rdepends Package #查看该包被哪些包依赖apt-get BUILD-DEP Package #安装相关的编译环境apt-get Source package #下载该包的源代码apt-get clean && apt-get AutoClean #清理下载文件的存档 && only cleans up outdated packages apt-get Check #检查是否有损坏的依赖dpkg-s filename #查找filename属于哪个软件包apt-file search Filenam E #查找filename属于哪个软件包apt-file list packagename #列出软件包的内容apt-file update #更新apt-file database DPKg-l #列出当前系统中所有的包. Can be used with the parameter less in Split-screen viewing (similar to RPM-QA) dpkg-l |grep-i "pkg" #查看系统中与 "pkg" associated packages (similar to RPM-QA | grep pkg) dpkg-s pkg #查询一个已安装的包的详细信息 (similar to Rpm-qi) dpkg-l pkg #查询一个已安装的软件包释放了哪些文件 (similar to RPM-QL) dpkg-s file #查询系统中某个文件属于 Which package (similar to RPM-QF) dpkg-c Pkg.deb #查询一个未安装的deb包将会释放哪些文件 (similar to RPM-QPL) dpkg-i Pkg.deb #查看一个未安装的deb包的详细信息 (similar to RPM-QPI) dpkg- I pkg.deb #手动安装软件包 (cannot solve the soft dependency problem, can be solved with apt-get-f install) Dpkg-r pkg #卸载软件包 (not a full uninstall, its configuration file also exists) Dpkg-p pkg #全部卸载 (cannot Solve the dependency problem) dpkg-reconfigure pkg #重新配置dpkg-x pkg.deb dir #将一个deb包解开至dir目录dpkg--pending--remove #移除多余的软件

　　

Force installation of a package (ignoring dependencies and other issues)

Dpkg-i pkg.deb--force-all    #可以参考dpkg--force-help

In addition, Ubuntu has another package management tool aptitude, the following are common usage

Aptitude Update   #更新可用的包列表 aptitude upgrade  #升级可用的包 aptitude dist-upgrade     #将系统升级到新的发行版 Aptitude Install Pkgname  #安装包 Aptitude Remove pkgname   #删除包 aptitude purge pkgname    #删除包及其配置文件 Aptitude search String    # Search package (equivalent to Yum list | grep pkg, important) Aptitude show Pkgname     #显示包的详细信息 (equivalent to Yum info pkg, important) aptitude clean            #删除下载的包文件 aptitude autoclean< c11/> #仅删除过期的包文件

Aptitude and Apt-get are complementary to each other, and there are some features on both sides.

Advantages of aptitude: Install, remove, reinstall (Apt-get without this function), show (Apt-get without this feature), search (Apt-get without this feature), hold (Apt-get without this feature), Unhold (Apt-get without this feature)

Advantages of Apt-get: source (aptitude without this function), BUILD-DEP (low version of aptitude without BUILD-DEP function)

Apt-get the same place as aptitude: Update, upgrade (Apt-get upgrade=aptitude Safe-upgrade, Apt-get dist-upgrade=aptitude Full-upgrgade)

In addition, if you want to search the network of BZIP2 software packages, with Apt-cache search bzip2, will search out a lot of clutter, and aptitude search bzip2 results are much more accurate. Because Apt-cache is based on full-text matching (including descriptions, etc.), aptitude is matched by file name.
