        "x-api-key: xyz"
    ]
};
const url = "https://myserver/hello";
CmdTemplate`curl ${opt1} ${url}`;

// all the argument is automatically stringify.

// similarly the utility function sh
async function task () {    
    const [stdout, stderr] = await sh`curl ${opt1} ${url}`;
    
    // use node's exec from spawn_process
    // by default runs with {shell: process.env['SHELL'], print: true}
    // if more fine control need, please use spawn
    
    // "print" is a custom property for piping the exec's stdout, stderr to process's stdio

    // to override option 
    await sh.withOptions({print: false})`echo hello world`
    // => nothing will be printed
