#!/bin/bash
# 用于批量制造 eth 账户

## Config #######
num=1000
eth_datadir=/data/eth
password='abcd@1234'

## Running #######
now=$(date +%s)
logfile=eth_keys_$now.log
txtfile=eth_account_$now.txt

if [ ! -d $eth_datadir ]; then
    mkdir -p $eth_datadir
fi

echo $password > /tmp/eth_pass

for i in $(seq 0 $num); do

    # --lightkdf 减少CPU和RAM消耗，更快，但降低kdf强度
    # --datadir  默认datadir在 /root/.ethereum/
    printf "Progress: [%d/%d]\r" $[i+1] $num
