process.argv


    process.argv 属性返回数组,其中包含启动 Node.js 进程时传入的命令行参数。 第一个元素将是 process.execPath。 如果需要访问 argv[0] 的原始值,请参阅 process.argv0。 第二个元素将是正在执行的 JavaScript 文件的路径。 其余元素将是任何其他命令行参数。

    The process.argv property returns an array containing the command-line arguments passed when the Node.js process was launched. The first element will be process.execPath. See process.argv0 if access to the original value of argv[0] is needed. The second element will be the path to the JavaScript file being executed. The remaining elements will be any additional command-line arguments.

    For example, assuming the following script for process-args.js:

    import { argv } from 'node:process';
    
    // print process.argv
    argv.forEach((val, index) => {
      console.log(`${index}: ${val}`);
    });const { argv } = require('node:process');
    
    // print process.argv
    argv.forEach((val, index) => {
      console.log(`${index}: ${val}`);
    });

    Launching the Node.js process as:

    $ node process-args.js one two=three four

    Would generate the output:

    0: /usr/local/bin/node
    1: /Users/mjr/work/node/process-args.js
    2: one
    3: two=three
    4: four
