Fix UUIDs incorrectly displayed by HP iLO

node-fixuuid.js

var rl = require('readline');
var fs = require('fs');

var i = rl.createInterface(process.stdin, process.stdout, null);

i.question("Enter the UUID to correct: ", function(answer) {

  var uuidArray = answer.split("-");

  // only the first half of the UUID is wrong, so iterate
  // over first 3 array values and reverse in pairs
  for ( var j = 0; j < 3; j++ ) {
    uuidArray[j] = uuidArray[j].match(/../g).reverse().join('');
  }

  var correctUUID = uuidArray.join("-").toLowerCase();

  console.log();
  console.log(correctUUID);

  // without these 2 lines, the program would run forever
  i.close();
  process.stdin.destroy();
});
