Node.js process.getgid() Method

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

Syntax:

process.getgid()

Parameters: This method does not accept any parameters.

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

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

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

Example 1:

// Node.js program to demonstrate the
// process.getgid() method

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

// Printing the numerical group
// identity of the Node.js process
console.log(process.getgid());

Output:

1000

Example 2:

// Node.js program to demonstrate the
// process.getgid() method

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

// Checking whether this method
// exists or not
if (process.getgid) {

  // Printing getgid() value
  console.log("The numerical group identity "
              + "of the Node.js process: "
              + process.getgid());
}

Output:

The numerical group identity of the Node.js process: 1000

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