Node.js process.setgid() Method Last Updated : 28 Apr, 2025 Suggest changes Share Like Article Like Report The process.setgid() method is an inbuilt application programming interface of the process module which is used to set the group identity of the Node.js process.Syntax: process.setgid(id) Parameters: This method accepts single parameter as mentioned above and described below: id: It is a required parameter that holds a String or an integer denotes either groupname or ID, if group name is passed, it blocks while resolving the associated numeric ID. Return: It does not return any value.Note: This function will only work on POSIX platforms. Not available on windows or android platforms so will cause an error i.e. TypeError, setgid is not a function.Below examples illustrate the use of process.setgid() method in Node.js:Example 1: javascript // Node.js program to demonstrate the // process.setgid() Method // Including process module const process = require('process'); // Printing the group identity of // the Node.js process that checks // whether the methods exists or not if (process.getgid && process.setgid ) { // Setting gid process.setgid(400); // Printing getgid() value console.log("The group identity of the Node.js" + " process:", process.getgid()); } Output: The group identity of the Node.js process: 400 Example 2: javascript // Node.js program to demonstrate the // process.setgid() Method // Including process module const process = require('process'); // Set gid and check whether the // method exists or not if (process.setgid) { // Within try catch try { process.setgid(696); console.log("gid has successfully been set"); } catch (err) { console.log("Failed to set gid:", err); } } // Check whether the method exists or not if (process.getgid) { // Printing getgid() value console.log("The group identity of the Node.js" + " process:", process.getgid()); } Output: gid has successfully been set The group identity of the Node.js process: 696 Note: The above program will compile and run by using the node filename.js command.Reference: https://nodejs.org/api/process.html#process_process_setgid_id G gekcho Follow Article Tags : Web Technologies Node.js Node.js-process-module Explore Node.js Tutorial 3 min read Introduction & Installation NodeJS Introduction 3 min read Node.js Roadmap: A Complete Guide 6 min read How to Install Node.js on Linux 6 min read How to Install Node.js on Windows 5 min read How to Install NodeJS on MacOS 6 min read Node.js vs Browser - Top Differences That Every Developer Should Know 6 min read NodeJS REPL (READ, EVAL, PRINT, LOOP) 4 min read Explain V8 engine in Node.js 7 min read Node.js Web Application Architecture 3 min read NodeJS Event Loop 5 min read Node.js Modules , Buffer & StreamsNodeJS Modules 5 min read What are Buffers in Node.js ? 4 min read Node.js Streams 4 min read Node.js Asynchronous ProgrammingAsync Await in Node.js 3 min read Promises in NodeJS 7 min read How to Handle Errors in Node.js ? 4 min read Exception Handling in Node.js 3 min read Node.js NPMNodeJS NPM 6 min read Steps to Create and Publish NPM packages 7 min read Introduction to NPM scripts 2 min read Node.js package.json 4 min read What is package-lock.json ? 3 min read Node.js Deployments & CommunicationNode Debugging 2 min read How to Perform Testing in Node.js ? 2 min read Unit Testing of Node.js Application 5 min read NODE_ENV Variables and How to Use Them ? 2 min read Difference Between Development and Production in Node.js 3 min read Best Security Practices in Node.js 4 min read Deploying Node.js Applications 5 min read How to Build a Microservices Architecture with NodeJS 3 min read Node.js with WebAssembly 3 min read Resources & ToolsNode.js Web Server 6 min read Node Exercises, Practice Questions and Solutions 4 min read Node.js Projects 9 min read NodeJS Interview Questions and Answers 15+ min read My Profile ${profileImgHtml} My Profile Edit Profile My Courses Join Community Transactions Logout Like
