You need to write like this

  .option('-a, --aaa <aValue>', 'option')
  .option('-b, --bbb <bValue>', 'option')
  .option('-c, --ccc <cValue>', 'option')
  .parse(process.argv);

You can then access the value using program.aaa

To access to the specific value to have to use program.args which is an array of the options that you have added (is in order to the options).

You need to specify that the option takes a value. Expanding on the answer by @yausername

// mycmd.js
var program = require('commander')

program
  .option('-a, --aaa <value>', 'option')
  .option('-b, --bbb <value>', 'option')
  .option('-c, --ccc <value>', 'option')
  .parse(process.argv);

console.log(`aaa is ${program.aaa}`);
console.log(`bbb is ${program.bbb}`);
console.log(`ccc is ${program.ccc}`);

$ mycmd -b bValue -c cValue -a aValue 
aaa is aValue
bbb is bValue
ccc is cValue
