YUM vs RPM for PACKAGE MANAGEMENT | LINUX YUM YUM Stands for Yellow dog Updater and Modifier.

YUM is an interactive, rpm based, open source package manager. YUM automatically performs system updates, including dependency analysis and obsolete processing based on “repository” meta data. It can also perform installation of new packages, removal of old packages and perform queries on the installed and /or available packages. It is capable of tracking the dependencies of package and installing them prior to installing the package (Which is user wanted to install). This simplifies the whole process (as we need to know only name of the package which want to install ) and no need to worry whether the required packages have been installed or not. Packages that can’t be found on the system are searched for in the repositories. Sample Commands for YUM Listing all available packages in the yum repository using list # yum list or # yum list all # yum list httpd # yum list updates Displays list of updated softwares. View Installed Packages # yum list installed

or

# rpm -qa

Prints all the packages which are installed on linux system.

POINTS TO NOTE : RPM and YUM are what really installs the packages . RPM cannot handle updated software installation automatically. The RPM

package manager is unable to track dependencies while YUM can. RPM

Cannot connect to online repositories

but Can connect to on-line

repositories to get latest software before installing the applications

I Strongly recommend don't use rpm , use yum. Preference always goes with using yum when rpm failed to install package with dependencies issue. Instructions are here http://public-yum.oracle.com/ To know more about yum http://yum.baseurl.org/wiki/YumCommands
