Node.js stats.ino Property

The stats.ino property is an inbuilt application programming interface of the fs.Stats class is used to get the "Inode" number of the file specified by the file system. Syntax:

stats.ino;

Parameters: This property does not have any parameter. Return Value: It returns a number or BigInt value which represents the "Inode" number of the file specified by the file system. Below examples illustrate the use of stats.ino property in Node.js: Example 1:

javascript

// Node.js program to demonstrate the   
// stats.ino Property

// Accessing fs module
const fs = require('fs');

// Calling stats.ino property from
// fs.Stats  class
// For files using stat
fs.stat('./filename.txt', (err, stats) => {
    if (err) throw err;
    console.log("using stat: the \"Inode\" "
        + "number of the file is  " + stats.ino);
});

// Using lstat
fs.lstat('./filename.txt', (err, stats) => {
    if (err) throw err;
    console.log("using lstat: the \"Inode\" "
        + "number of the file is  " + stats.ino);
});

// For directories using stat
fs.stat('./', (err, stats) => {
    if (err) throw err;
    console.log("using stat: the \"Inode\" "
        + "number of the file is  " + stats.ino);
});

//using lstat
fs.lstat('./', (err, stats) => {
    if (err) throw err;
    console.log("using lstat: the \"Inode\" "
    + "number of the file is  " + stats.ino);
});

Output:

using stat: the "Inode" number of the file is  1125899907737972
using lstat: the "Inode" number of the file is  1125899907737972
using stat: the "Inode" number of the file is  14918173765820528
using lstat: the "Inode" number of the file is  14918173765820528

Example 2:

javascript

// Node.js program to demonstrate the   
// stats.ino Property

// Accessing fs module
const fs = require('fs').promises;
 
// Calling stats.ino property from
// fs.Stats class
(async() => {
  const stats = await fs.stat('./filename.txt');
 
  // Using stat synchronous
  console.log("The \"Inode\" number "
    + "of the file is  "+stats.ino);
})().catch(console.error)

Output:

The "Inode" number of the file is  1125899907737972

Note: The above program will compile and run by using the node filename.js command and use the file_path correctly. Reference: https://nodejs.org/api/fs.html#fs_stats_ino
