在NodeJS中删除文本文件中的特定行

const fs = require('fs');

function deleteSpecificLine(filePath, lineToRemove) {
  // Read file
  const content = fs.readFileSync(filePath, 'utf-8');

  // Split content into lines
  const lines = content.split('\n');

  // Filter out the line to remove
  const filteredLines = lines.filter((line) => line !== lineToRemove);

  // Join lines back into a string
  const updatedContent = filteredLines.join('\n');

  // Write updated content back to file
  fs.writeFileSync(filePath, updatedContent, 'utf-8');

  console.log(`Specific line "${lineToRemove}" has been removed from the file.`);
}

// Usage
const filePath = 'path/to/file.txt';
const lineToRemove = 'This is the line to remove';

deleteSpecificLine(filePath, lineToRemove);
