Node.js process.setegid() Method Last Updated : 12 Oct, 2021 Suggest changes Share Like Article Like Report The process.setegid() method is an inbuilt application programming interface of the process module which is used to set the numerical effective group identity of the Node.js process. Syntax: process.setegid(id) Parameters: This method accept single parameter as mentioned above and described below: id: It is a required parameter. It is a string or an integer denotes either groupname or ID, if group name is passed, it blocks while resolving the associated a numeric ID. Return: It does not return anything. Note: This function will only work on POSIX platforms. Not available on windows or android platforms so will cause an error i.e. TypeError, setegid is not a function. Below examples illustrate the use of process.setegid() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // process.setegid() Method // Include process module const process = require('process'); // Printing the numerical effective group // identity of the Node.js process checking // whether the methods exists or not if (process.getegid && process.setegid ) { // Setting gid process.setegid(400); // Printing getegid() value console.log("The numerical effective group" + " identity of the Node.js process:" + process.getegid()); } Output: The numerical effective group identity of the Node.js process: 400 Example 2: javascript // Node.js program to demonstrate the // process.setegid() Method // Include process module const process = require('process'); // Checking whether the method // exists or not if (process.setegid) { try { process.setegid(696); console.log("gid has successfully been set"); } catch (err) { console.log("Failed to set gid:", err); } } // Checking whether the method exists or not if (process.getegid) { // Printing getegid() value console.log("The numerical effective group identity" + " of the Node.js process:" + process.getegid()); } Output: gid has successfully been set The numerical effective group identity of the Node.js process: 696 Note: The above program will compile and run by using the node filename.js command.
