Node.js fs.linksync() Method

Node.js fs.readlinkSync() Method

Node.js fs.futimesSync() Method

The fs.linkSync() method is used to synchronously create a hard link to the specified path. The hard link created would still point to the same file even if the file is renamed. The hard links also have the actual file contents of the linked file.

Syntax:

fs.linkSync( existingPath, newPath )

Parameters: This method accept two parameters as mentioned above and described below:

  • existingPath: It is a string, buffer or URL which represents the file to which the symlink has to be created.
  • newPath: It is a string, buffer or URL which represents the file path where the symlink will be created.

Below examples illustrate the fs.linkSync() method in Node.js:

Example 1: This example creates a hard link to a file.




// Node.js program to demonstrate the
// fs.linkSync() method
  
// Import the filesystem module
const fs = require('fs');
  
console.log("Contents of the text file:");
console.log(fs.readFileSync('example_file.txt', 'utf8'));
  
fs.linkSync(__dirname + "\\example_file.txt", "hardlinkToFile", 'file');
  
console.log("\nHard link created\n");
console.log("Contents of the hard link created:");
console.log(fs.readFileSync('hardlinkToFile', 'utf8')); 






                        









													
													
												

												
												

													
													
Output:

													
													
												

												
												

													
													
Contents of the text file:
Hello w3wiki

Hard link created

Contents of the hard link created:
Hello w3wiki

													
													
												

												
												

													
													
Example 2: This example creates a hard link to a file and deletes the original file. The contents of the original file can be still accessed through the hard link.

console.log("Contents of the text file:"); 


console.log(fs.readFileSync('example_file.txt', 'utf8'));

console.log("\nHard link created\n"); 


console.log("Contents of the hard link created:"); 


console.log(fs.readFileSync('hardlinkToFile', 'utf8')); 


  


console.log("\nDeleting the original file"); 


fs.unlinkSync("example_file.txt"); 


  


console.log("\nContents of the hard link created:"); 


console.log(fs.readFileSync('hardlinkToFile', 'utf8')); 



















                        







                        









													
													
												

												
												

													
													
Output:

													
													
												

												
												

													
													
Contents of the text file:
Hello w3wiki

Hard link created

Contents of the hard link created:
Hello w3wiki

Deleting the original file

Contents of the hard link created:
Hello w3wiki
