yum
yum - Yellowdog Updater Modified Synopsis yum [options] [command] [package …] Description yum is an interactive, rpm based, package manager. It can automatically perform system updates, including dependency analysis and obsolete processing based on “repository” metadata. It can also perform installation of new packages, removal of old packages and perform queries on the installed and/or available packages among many other commands/services (see below). yum is similar to other high level package managers like apt-get and smart. While there are some graphical interfaces directly to the yum code, more recent graphical interface development is happening with PackageKit and the gnome-packagekit application. command is one of: * install package1 [package2] […] * update [package1] [package2] […] * update-to [package1] [package2] […] * check-update * upgrade [package1] [package2] […] * upgrade-to [package1] [package2] […] * distribution-synchronization [package1] [package2] […] * remove | erase package1 [package2] […] * list […] * info […] * provides | whatprovides feature1 [feature2] […] * clean [packages | metadata | expire-cache | rpmdb | plugins | all] * makecache * groupinstall group1 [group2] […] * groupupdate group1 [group2] […] * grouplist [hidden] [groupwildcard] […] * groupremove group1 [group2] […] * groupinfo group1 […] * search string1 [string2] […] * shell [filename] * resolvedep dep1 [dep2] […] * localinstall rpmfile1 [rpmfile2] […] (maintained for legacy reasons only - use install) * localupdate rpmfile1 [rpmfile2] […] (maintained for legacy reasons only - use update) * reinstall package1 [package2] […] * downgrade package1 [package2] […] * deplist package1 [package2] […] * repolist [all|enabled|disabled] * version [all | installed | available | group-* | nogroups* | grouplist | groupinfo] * history [info|list|packages-list|packages-info|summary|addon-info|redo|undo|rollback|new|sync|stats] * load-transaction [txfile] * check * help [command]
