monero-wallet-cli commands

First off, to start the CLI, type:

$ monero-wallet-cli

If there's no wallet file in the current directory it will be created for you on startup, otherwise you'll need to choose a wallet name and one will be created for you.

Important: Monero wallets consist of two files, a wallet file and a keys file. For example if your wallet is called my-wallet, the files will be my-wallet (wallet data file) and my-wallet.keys (key file). Both of these files are needed. Once in the wallet REPL, the following commands are available:

npodonnell

#!/usr/bin/bash

INTERVAL=10
SRC_DIRS=( Documents )
DEST_HOST=192.168.0.1
DEST_USER=user
DEST_DIR="~/backup" # Quotes are important!

if [ -e ~/.syncfiles.lock ]; then
    echo "lockfile detected"

Monitor outgoing DNS traffic:

Bitcoin Core Codebase Notes

Transaction Signing

MutableTransactionSignatureCreator (src/script/sign.cpp) seems to be where the sighash is created. There is one constructor which takes a transaction (txToIn), an input index (nInIn), and amount, and a sighash type (eg. SIGHASH_ALL).
