Node.js - rename multiple files
0 points
In this article, we would like to show you how to rename multiple files in Node.js.
Quick solution:
xxxxxxxxxx1
const fs = require('fs');2
3
const src = 'C:\\projects\\app\\Users';4
const files = fs.readdirSync(src);5
6
for (const file of files) {7
fs.rename(oldPath, newPath, callback);8
}Note:
If the
newPathalready exists, it will be overwritten.
Let's say we have the following project structure:
xxxxxxxxxx1
/app/2
└── Users/3
├── usr1.js4
├── usr2.js5
└── usr3.jsTo rename usr.js files we will use:
for...ofstatement to iterate the Users/ directory,fs.readdirSync()to get the file names from Users/ directory,fs.rename()to actually rename the usr.js files.
xxxxxxxxxx1
const fs = require('fs');2
3
const src = 'C:\\projects\\app\\Users';4
const files = fs.readdirSync(src);5
6
for (const file of files) {7
if (file.startsWith('usr')) {8
fs.rename(9
src + '/' + file,10
src + '/' + file.replace('usr', 'user'),11
err => {12
console.error(err)13
}14
)15
}16
}Result:
xxxxxxxxxx1
/app/2
└── Users/3
├── user1.js4
├── user2.js5
└── user3.js
