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:
// 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:
// 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.
