Probably need to add a console.error(chalk.red(e)); to notify the user of the error

console.error(e);
process.exit(1);
}
from = config.from;
to = config.to;
if (typeof config.files === 'string') {
config.files = [config.files];
}
files = config.files;
}

if (!from === undefined) {
from = argv._.shift();
}
if (!to === undefined) {
to = argv._.shift();
}
if (!files) {
files = argv._;
}

if (!from === undefined || !to === undefined) {
console.error(chalk.red('Must set from & to options'));
process.exit(1);
}
if (!files) {
console.error(chalk.red('Must pass a list of files'));
process.exit(1);
}

//Single star globs already get expanded in the command line
const files = argv._.reduce((files, file) => {
files = files.reduce((files, file) => {
return files.concat(file.split(','));
}, []);
