This command allows a user to increase the fee on a wallet transaction T, creating a "bumper" transaction B. T must signal that it is BIP-125 replaceable. T's change output is decremented to pay the additional fee. (B will not add inputs to T.) T cannot have any descendant transactions. Once B bumps T, neither T nor B's outputs can be spent until either T or (more likely) B is mined. Includes code by @jonasschnelli and @ryanofsky
