uid-number

Convert username to UID

This feature allows you to convert a given username to its corresponding numeric user ID (UID). The function takes a username as its first argument and a callback as the second argument. The callback receives an error object (if any), the UID, and the GID associated with the username.

const uidNumber = require('uid-number');
uidNumber('username', (err, uid, gid) => {
  if (err) {
    console.error('Error getting UID:', err);
  } else {
    console.log('UID:', uid);
  }
});

Convert group name to GID

This feature allows you to convert a given group name to its corresponding numeric group ID (GID). The function takes a group name as its second argument and a callback as the third argument. The callback receives an error object (if any), the UID (which is undefined in this case), and the GID associated with the group name.

const uidNumber = require('uid-number');
uidNumber(undefined, 'groupname', (err, uid, gid) => {
  if (err) {
    console.error('Error getting GID:', err);
  } else {
    console.log('GID:', gid);
  }
});
