Truffle CLI exec with arguments

Context

truffle exec runs a script inside the Truffle environment but does not forward arbitrary CLI flags to your script — only Truffle's own options like --network are parsed. You can read raw arguments from process.argv and parse them yourself with yargs-parser, which leaves Truffle's built-in flags untouched.

Usage

const argv = require("yargs-parser")(process.argv.slice(2));

module.exports = async (callback) => {
  const name = argv?.n || "World";
  callback(`Hello ${name}`);
};

truffle exec hello.js -n=Dung --network development

• -n=Dung: Custom argument
• --network: Standard Truffle option (still works)
