文本文件如何去除回车

去除文本文件中的回车符可以通过多种编程语言实现。以下是一些常见编程语言的示例：

Python

```python

读取文件

with open('yourfile.txt', 'r') as file:

content = file.read()

去除回车符

content = content.replace('rn', '').replace('n', '')

写回文件

with open('yourfile.txt', 'w') as file:

file.write(content)

```

JavaScript（Node.js）

```javascript

const fs = require('fs');

// 读取文件

const data = fs.readFileSync('yourfile.txt', 'utf8');

// 去除回车符

const content = data.replace(/rn/g, '').replace(/n/g, '');

// 写回文件

fs.writeFileSync('yourfile.txt', content);

```

Java

```java

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

public class RemoveNewlines {

public static void main(String[] args) {

String inputFileName = "yourfile.txt";

String outputFileName = "yourfile_cleaned.txt";

try (BufferedReader reader = new BufferedReader(new FileReader(inputFileName));

BufferedWriter writer = new BufferedWriter(new FileWriter(outputFileName))) {

String line;

while ((line = reader.readLine()) != null) {

writer.write(line);
