Found Bitcoin-QT.

First I check the executable is there

from Mac OS dir $ ls
Bitcoin-Qt

Then I run this

Bitcoin-Qt -zapwalletxes

I get this....

-bash: Bitcoin-Qt: command not found

I matched case on the ls, have to be missing something

try

./Bitcoin-Qt -zapwalletxes

You're slow, we already go past that. The problem OP now has is that zapwallettxes is not removing his unconfirmed transactions. I have been thinking about it but I don't know why that is happening.

Ya saw that and deleted it. Hadnt refreshed in a while I guess

I have never used the zapwallet command. I still use gavins bitcointools to remove txes from a wallet. But then we go down the road of getting python installed for op

https://github.com/gavinandresen/bitcointools

EDIT:

Depending on how many addresses you have you could run a "listunspent" then dump the private key for every address with a balance. Then import them to a new wallet. If you have more than a dozen addresses this would just be a pain. Backup both wallets and dont forget to dump the key to the change address from the unconfirmed transactions

I have run zapwalletxes both online and offline if anyone is interested.

I got the private key using the bitcoin-qt debug window on one of the hung txns using. I tried importing that key into another Bitcoin-qt client but it said the the key was not in the acceptable import format. I have no idea how to get such a format.

i can easily get all the keys, but I need a way to format them so i can import them back, strange the format out is not the same as the format in.... or if it is can someone tell me and I will see what i may have done wrong.

try running it with -zapwallettxes=2 instead of just -zapwallettxes. I'm not sure if that will help.

Added this ./ to the front of Bitcoin-Qt -zapwalletxes

It launched Bitcoin-Qt.... no idea what is happening now.. hopefully launching with a delete on my unconfirmed txns

When everything loads, check the transaction history and all of the unconfirmed transactions that were there should be gone. Then you can shut down bitcoin core and restart it normally. Everything should work and you can then resend all of your transactions.

This did not happen, the most recent transaction is now listed as status "conflicted", no idea what this means....dafuq

The next four transactions are listed as "unconfirmed" still with zero confirmations....

Starting to make me nervous with conflicted status, someone spending my coins.... Sad

Do i need to shutdown my bitcoin-qt client first? navigate to correct directory???

You shouldn't need to navigate to the directory, but bitcoin core needs to be shutdown first.

I did shutdown the client, but getting command not found when I run from Terminal root dir

Looked in /Library/Application Support for Bitcoin directory but cannot find it.... argh

I think it should be in /applications, but I could be wrong. I don't use macs.

It is in /Applications but it has some weird Mac crap going on. the file is Bitcoin-qt.app

Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt

seems to be the target... about to do this thing.. fml

running this from the debug window says method not found

bitcoind -zapwallettxes

Just run zapwallettxes (no dash, no bitcoind)

Running Macbook Bitcoin-QT client, from debug window I type and get

zapwallettxes
Method not found (code -32601)

If you are running the qt you need to start bitcoin-qt if im not mistaken not bitcoind but its been a few years since I used bitcoin-qt

I just confirmed bitcoind accepts -zapwallettxes

try bitcoin-qt -zapwallettxes

AFAIK, its impossible to cancel an unconfirmed bitcoin transaction and it was the nature of bitcoin. If it was a double spend, it'll automatically been rejected by the node.

If you want to remove the transaction from your wallet, you can use the -zapwallettxes command line option:

https://en.bitcoin.it/wiki/Running_Bitcoin

Code:

-zapwallettxes=  Delete all wallet transactions and only recover those part of the blockchain through -rescan on startup

If most nodes have already heard about your first transaction, you may find it difficult to "double spend with a bigger txn fee ahead of this transaction". Most nodes, miners, and mining pools will refuse to accept the new higher fee transaction while they still have the old transaction in their memory pool.

Even if you remove the transaction from your wallet, it doesn't guarantee that the transaction is "cancelled". It's possible that a miner (or mining pool) that has already heard about the original transaction will confirm it before it is dropped from everyone's memory pool.

What do I put in

What are the risks of doing this, can i corrupt my wallet in any way?

I have some unconfirmed transactions that are sitting for hours. I want them gone, what can i do?

5b788baaf29eb5da59b01704179d5ebfb05f0ea3dea79482b76984b2001a7c4c-000

I don't want it pushed, i want it gone....

What wallet did you send the transaction from?

Can I get my address private key off bitcoin-qt?

Thinking a second strategy is to double spend with a bigger txn fee ahead of this transaction. If i can import my key into blockchain or some other wallet service i can double spend from there i think....

Open up the debug console, Help > Debug Window > console tab and then type into the box

Code:

dumpprivkey

Where

is the address whose private key you want.

If the wallet has a password on it, do

Code:

walletpassphrase  120

where is the passphrase to your wallet BEFORE the command above. This will unlock your for 120 seconds so in that time you need to do the dumpprivkey to get the private key in Wallet Import Format.
