node.js process.title用法及代码示例


process.title属性是流程模块的内置应用程序编程接口,用于获取和设置流程的标题。

用法:

process.title

返回值:此属性返回一个字符串值,该值指定进程的标题,当前值为“ ps”。


注意:将新值分配给此属性将修改当前值。不同的平台可能会限制进程标题的最大长度。

以下示例说明了Node.js中process.title属性的使用:

范例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

范例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:上面的程序将通过使用node filename.js命令。
