I catch myself sometimes needing to temporarily install a package on a server (e.g. Firefox) but when I do it installs a ton of dependencies only needed for this one temporary package.
# yum install firefox ... Resolving Dependencies ... --> Finished Dependency Resolution Dependencies Resolved ... Transaction Summary ================================================================================================================================================================================ Install 1 Package (+47 Dependent packages)
So, then when I go to remove the temporary package, I now also need to remove all of the dependent packages that it just installed. That can be a pain to do manually.
Thankfully, YUM has a method to remove the package and all of it's otherwise unused dependent packages:
# yum autoremove firefox ... Resolving Dependencies ... --> Finished Dependency Resolution Dependencies Resolved ... Transaction Summary ================================================================================================================================================================================ Remove 1 Package (+47 Dependent packages)
