== Dependencies/Package ==
**First** make sure the yum-utils package is installed:
<sxh bash>
rpm -qa | grep yum-utils
</sxh>
== Installing yum-utils ==
<sxh bash>
# yum search yum | grep utils
yum-utils.noarch : Utilities based around the yum package manager
</sxh>
<sxh bash>
yum install yum-utils.noarch
</sxh>

Example: Package NOT installed
<sxh bash>
# yum search php56u | grep ^php56u.x86_64
php56u.x86_64 : PHP scripting language for creating dynamic web sites
</sxh>
<sxh bash>
# rpm -q php56u.x86_64 --changelog
package php56u.x86_64 is not installed

<sxh bash>
# repoquery php56u.x86_64 --changelog | head
