process.setgroups(groups): void

Attributes

groups:integer[]

The process.setgroups() method sets the supplementary group IDs for the Node.js process. This is a privileged operation that requires the Node.js process to have root or the CAP_SETGID capability.

The groups array can contain numeric group IDs, group names, or both.

import process from 'node:process';

if (process.getgroups && process.setgroups) {
  try {
    process.setgroups([501]);
    console.log(process.getgroups()); // new groups
  } catch (err) {
    console.error(`Failed to set groups: ${err}`);
  }
}
