This flag allows you to test your command-line options. It can help you see which indices will be caught by operations without actually performing those operations. Starting in v3.1.0, the term (CLOSED) will appear next to indices which are in a closed state.


  • --dry-run Do not actually perform the action.

This flag must come before any command.


Do a dry-run test of deleting indices:

curator --dry-run delete indices <<index selection parameters>>
