Scripts for using Blackcoin from the Command Line Interface

Scripts for using Blackcoin from the Command Line Interface

Blackcoin-More (Linux)

Since we have been having "dust storms" I wrote a script for cleaning dust out of wallets. And, because some Legacy clients have been going off chain I wrote a script for comparing the local chain with the BlackcoinNL hosted explorer. After doing that I simply combined them all into a single script with the other scripts I use regularly.

I put symlinks into /usr/local/bin/ for blackmored, blackmore-cli, and blk (the script below). This simple shell script that improves my security (by not saving my password in a file or memory), and simplifies regular tasks.

The alias alias blkc='blackmore-cli' in .bashrc is useful as well.

Make sure you chmod 700 $USER all-the-things (or 755)

blk

#!/bin/bash

usage="Usage: blk [ info | stake | latest | dust | past24 ] \n \n
	info: Check basic info. \n
	stake: Enables staking; Passes password without storing it in memory. \n
	latest: Compares latest block with the BlackcoinNL hosted block explorer. \n
	dust: Prunes dust from wallet. Dust is defined as less than .0001BLK. Requires jq. \n
	past24: Shows staking numbers from the past 24hrs. \n"

blkc='/usr/local/bin/blackmore-cli -datadir=/var/lib/.blackmore/'

esac

jq is required for the dust pruning script, and can be found via your favorite package manager.

Blackcoin-Legacy (Windows)

The script below is almost exactly the same as the blk latest command above, but it's written with blackcoind.exe for Windows, which is not in the user PATH.

I don't use Windows, but I'm told the easiest way to get bash on Windows is to install https://gitforwindows.org/

Then you can just copy paste this line (while in the directory with blackcoind.exe):

latest=$(./blackcoind.exe getblockcount) && \
	blacksight=$(curl -s https://node.blackcoin.io/insight-api/block-index/$latest? |  cut -d '"' -f4) && \
	blackcoin=$(./blackcoind.exe getblockhash $latest) && \
	diff -sy  --label Local  <(echo $blackcoin)  --label Explorer <(echo $blacksight)

Mac

Mac dropped their old OS for Unix a while back, so the script at the top should work just fine for Blackcoin-More, and can be adjusted for Blackcoin-Legacy if needed.

Again, jq does not come installed, so you need to pick that up:

  1. First, install the brew package manager: (Link)
  2. brew install jq

OR

Install from: http://macappstore.org/jq/
