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:
// 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.
