How to apply RBF (Replace-by-Fee) I got a stuck transaction and would like to clear this. I found many information about RBF (Replace-by-Fee) how it works etc. So i think this might be the best option to get my transaction going.  

Unfortunately i couldnt find any information about how to apply this command to the existing unconfirmed and zero-fee transaction. Please advise.  

THank you so much

This page contains


  ..tools to test out replace-by-fee functionality. You'll need a local
  node with the replace-by-fee patch.


E.g. 
To double spend ./double-spend.py &lt;address&gt; &lt;amount&gt;

To just increase fee ./bump-fee.py &lt;txid&gt; etc.
