You want to save your time because you are not Bash expert (yet)?

(async function () {
var results = await Run(seriesOfCommands());
console.log();
console.log(`Summary:`);
console.log(`===`);
console.log(`executed ${results.length} commands`);
})();
async function* seriesOfCommands() {
// get my IP address
var myIp = yield Command('curl --silent https://canihazip.com/s');
console.log(`\t\(^ ^)/ my IP is ${myIp.value}`);
// get a Quote of the Day
var quoteOfTheDay = yield Command(`curl --silent -X GET --header 'Accept: application/json' 'https://quotes.rest/qod'`);
var quote = JSON.parse(quoteOfTheDay.value).contents.quotes[0];
console.log(`\t"${quote.quote}" -- ${quote.author}`);
