Node.js process.getegid() Method

The process.getegid() method is an inbuilt application programming interface of the process module which is used to get the numerical effective group identity of the Node.js process.

Syntax:

process.getegid()

Parameters: This method does not accept any parameters.

Return Value: It returns an object specifying the numerical effective group identity of the Node.js process.

Note: This function will only work on POSIX platforms. Not available on windows or android platforms so it will cause an error i.e. TypeError, getegid is not a function.

Below examples illustrate the use of process.getegid() method in Node.js:

Example 1:

// Node.js program to demonstrate the
// process.getegid() Method

// Include process module
const process = require('process');

// Print the numerical effective group
// identity of the Node.js process
console.log(process.getegid());

Output:

0

Example 2:

// Node.js program to demonstrate the
// process.getegid() Method

// Include process module
const process = require('process');

// Check 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:

The numerical effective group identity of the Node.js process: 0

Note: The above program will compile and run by using the node filename.js command.
