In https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/ several common CLI tools for OCP can be downloaded, including oc and kubectl. The different CLI tools are not presented consistently - for instance oc-mirror is listed without a version where ccoctl, openshift-client and openshift-install are. 

"latest" - suspect every OCP version going back some time have the same issue    

1. Head to https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/
2. Try to find oc-mirror-4.17.14.tar.gz - it's not there.
3. Try to find openshift-client-linux-4.17.4.tar.gz and it's there

Attempt to make a script that downloads the latest CLI for every tool we have. The naming standard isn't consistent making the script unnecessarily complex.    

Consistent naming - "cli tool name"-arch would suffice as the directory name either has the version number or is the latest, which means you aren't looking for a particular version. Every CLI tool executable available for download should follow the same template.
