Rename all files in a folder with NodeJS

rename.js

const { join } = require('path');
const { readdirSync, renameSync } = require('fs');
const [dir, search, replace] = process.argv.slice(2);
const match = RegExp(search, 'g');
const files = readdirSync(dir);

files
  .filter(file => file.match(match))
  .forEach(file => {
    const filePath = join(dir, file);
    const newFilePath = join(dir, file.replace(match, replace));

    renameSync(filePath, newFilePath);
  });

// Usage
// node rename.js path/to/directory 'string-to-search' 'string-to-replace'

If you have spaces in the filenames make sure that your strings to search and replace are wrapped in 's (or "s).

Example:

node rename.js ./folder/ 'file-name with-spaces' 'file-name-without-spaces'

If you have spaces in your folder name, then you need to escape the spaces. On UNIX based systems (such as MacOS and Linux) you can escape by adding a \ in front of the space. Like this:

node rename.js ./folder\ with\ spaces\ in\ the\ name/ 'file-name with-spaces' 'file-name-without-spaces' 

The examples above are with a folder structure like this:

📦 project
┗ 📜 rename.js    
┣ 📂 folder with spaces in the name
┃ ┗ 📜 file-name-without-spaces copy 2.txt
┃ ┗ 📜 file-name-without-spaces copy 3.txt
┃ ┗ 📜 file-name-without-spaces copy 4.txt
┃ ┗ 📜 file-name-without-spaces copy 5.txt
┃ ┗ 📜 file-name-without-spaces copy 6.txt
┃ ┗ 📜 file-name-without-spaces copy 7.txt
┃ ┗ 📜 file-name-without-spaces copy 8.txt
┃ ┗ 📜 file-name-without-spaces copy 9.txt
┃ ┗ 📜 file-name-without-spaces copy 10.txt
┃ ┗ 📜 file-name-without-spaces copy 11.txt
┃ ┗ 📜 file-name-without-spaces copy 12.txt
┃ ┗ 📜 file-name-without-spaces.txt

I would ask about pdf file !

I have a pdf file and I would to generate QR code when rename file. ex: file name is 12345678 the QR code must represent this value .
note : programing language that used in adobe acrobat pro dc is JavaScript

@Amjad-ND what you're asking has nothing to do with the code shown in this gist.
I would suggest going to Stackoverflow or any similar website and try to find some resources/ideas which will help you accomplish your task.

Thank you man
