hi leroygsmith
another possibility is to Uninstall Splunk Enterprise manually
if you can't use package management commands, use these instructions to uninstall Splunk Enterprise.
Note: These instructions will not remove any init scripts that have been created
1. Stop Splunk Enterprise.
$SPLUNK_HOME/bin/splunk stop
2. Find and kill any lingering processes that contain "splunk" in its name.
for macos
kill -9 `ps ax | grep splunk | grep -v grep | awk '{print $1;}'`
3. Remove the Splunk Enterprise installation directory, $SPLUNK_HOME. For example:
Note: For Mac OS, you can also remove the installation directory by dragging the folder into the trash.
4. Delete the splunk user and group, if they exist.
