Port Release

This feature helps you quickly release occupied ports without manually searching for and terminating processes.

Usage

1. Run create-yc-cmd
2. Select the "Free Port" option
3. Enter the port number you want to release
4. The tool will automatically find and terminate the processes occupying the port

How It Works

This feature uses PowerShell commands to find processes occupying the specified port and then uses the taskkill command to terminate these processes.

// Use Test-NetConnection to check if the port is in use
function isPortInUse(port) {
  const command = `powershell -Command "Test-NetConnection -ComputerName localhost -Port ${port}"`
  const result = execSync(command, { encoding: 'utf-8' })
  return result.includes('TcpTestSucceeded : True')
}

// Get the process IDs that occupy the port
function getPIDs(port) {
  const command = `powershell -Command "(Get-NetTCPConnection -LocalPort ${port}).OwningProcess | Select-Object -Unique"`
  const result = execSync(command, { encoding: 'utf-8' })
  return result
    .split(/\r?\n/)
    .filter((line) => line.trim() !== '')
    .map((pid) => parseInt(pid, 10))
    .filter((pid) => !isNaN(pid))
}
