Node.js process.title 属性
原文:https://www . geesforgeks . org/node-js-process-title-property/
流程标题属性是流程模块的内置应用编程接口，用于获取和设置流程标题。
语法:
process.title
返回值:该属性返回一个指定进程标题的字符串值，当前值为' ps '。
注意:为该属性赋予新值将修改当前值。不同的平台可以对进程标题的最大长度施加限制。
下面的例子说明了流程标题属性在 Node.js 中的使用:
例 1:
// Node.js program to demonstrate the
// process.title property
// Include process module
const process = require('process');
// Printing process.title property value
console.log("PID: " + process.pid +
" process title is " + process.title);
输出:
PID: 8852 process title is Command Prompt - node title_1
例 2:
// Node.js program to demonstrate the
// process.title property
// Include process module
const process = require('process');
// Printing process.title property value
console.log("Before modification: PID: " + process.pid
+" process title is " + process.title);
// Setting new process title value
process.title = "gekchosCustomProcess";
// Printing process.title value after modification
console.log("After modification: PID: " + process.pid
+ " process title is " + process.title);
输出:
Before modification: PID: 14012 process title is Command Prompt - node title_2
After modification: PID: 14012 process title is gekchosCustomProcess
注意:以上程序使用node filename.js命令编译运行。
