process.execArgv

• <string[]>

process.execArgv 属性返回 Node.js 进程启动时传入的一组特定于 Node.js 的命令行选项。 这些选项不会出现在 process.argv 属性返回的数组中，也不包括 Node.js 可执行文件、脚本名称或脚本名称后面的任何选项。 这些选项可用于衍生与父进程具有相同执行环境的子进程。

$ node --harmony script.js --version

process.execArgv 的结果：

['--harmony']

process.argv 的结果：

['/usr/local/bin/node', 'script.js', '--version']

• <string[]>

The process.execArgv property returns the set of Node.js-specific command-line options passed when the Node.js process was launched. These options do not appear in the array returned by the process.argv property, and do not include the Node.js executable, the name of the script, or any options following the script name. These options are useful in order to spawn child processes with the same execution environment as the parent.

$ node --harmony script.js --version

Results in process.execArgv:

['--harmony']

And process.argv:

['/usr/local/bin/node', 'script.js', '--version']
