How to differentiate between default reports/dashboards/alerts provided by splunk and one which is modified/customized/created by any user?

[kunalg]

I need to export all reports/dashboards created/modified by 7 users (including admin's modified and excluding admin's default and "nobody" owner)

[sudosplunk]

All default stuff shipped by splunk will be stored under default directories. Any objects created by user will be saved under $SPLUNK_HOME/etc/users/<user>/<app>/local OR $SPLUNK_HOME/etc/apps/<app>/local/(if the user shared the object at app-level).
