same message.

But then i deleted the : before the 0 and I got this:

like this:

umbrel:/$ lncli wallet bumpfee --sat_per_vbyte 20 b1d2a1d3ea96c2655dbec275c77dd86c5a223c700bd75522221e24d4823ef46e 0

and got this:

NAME:

lncli wallet bumpfee - Bumps the fee of an arbitrary input/transaction.

USAGE:

lncli wallet bumpfee [command options] outpoint

DESCRIPTION:

This command takes a different approach than bitcoind's bumpfee command.

lnd has a central batching engine in which inputs with similar fee rates

are batched together to save on transaction fees. Due to this, we cannot

rely on bumping the fee on a specific transaction, since transactions

can change at any point with the addition of new inputs. The list of

inputs that currently exist within lnd's central batching engine can be

retrieved through lncli wallet pendingsweeps.

When bumping the fee of an input that currently exists within lnd's

central batching engine, a higher fee transaction will be created that

replaces the lower fee transaction through the Replace-By-Fee (RBF)

policy.

This command also serves useful when wanting to perform a

Child-Pays-For-Parent (CPFP), where the child transaction pays for its

parent's fee. This can be done by specifying an outpoint within the low

fee transaction that is under the control of the wallet.

A fee preference must be provided, either through the conf_target or

sat_per_vbyte parameters.

Note that this command currently doesn't perform any validation checks

on the fee preference being provided. For now, the responsibility of

ensuring that the new fee preference is sufficient is delegated to the

user.

The force flag enables sweeping of inputs that are negatively yielding.

Normally it does not make sense to lose money on sweeping, unless a

parent transaction needs to get confirmed and there is only a small

output available to attach the child transaction to.

OPTIONS:

--conf_target value the number of blocks that the output should be swept on-chain within (default: 0)

--sat_per_vbyte value a manual fee expressed in sat/vbyte that should be used when sweeping the output (default: 0)

--force sweep even if the yield is negative
