Check Progress within Geth Javascript Console

var lastPercentage = 0;
var lastBlocksToGo = 0;
var timeInterval = 10000;
setInterval(function () {
    var percentage = eth.syncing.currentBlock / eth.syncing.highestBlock * 100;
    var percentagePerTime = percentage - lastPercentage;
    var blocksToGo = eth.syncing.highestBlock - eth.syncing.currentBlock;
    var bps = (lastBlocksToGo - blocksToGo) / (timeInterval / 1000);
    var etas = 100 / percentagePerTime * (timeInterval / 1000);
    var etaM = parseInt(etas / 60, 10);
    console.log(parseInt(percentage, 10) + '% ETA: ' + etaM + ' minutes @ ' + bps + 'bps');
    lastPercentage = percentage;
    lastBlocksToGo = blocksToGo;
console.log("Remaining Blocks: " + (eth.syncing.highestBlock - eth.syncing.currentBlock));
