The yum command has access to repositories where tons of packages are kept and can install, upgrade, or remove them for you automatically. Yum also takes care of resolving and installing any dependencies for
you, which the rpm command can’t do, following are basic commands for yum management.
clean Removes cached data
erase Removes a package from the system
grouplist Displays available package groups
groupinstall Installs the packages within a group
info Displays information about a package
install Installs a package on the system
search Enables you to search for a package
update Updates a package
You can use the grouplist command to get a listing of all available “groups”:
# yum grouplist
# yum groupinstall Emacs
# yum groupinstall “Development Tools”
