在Linux上:如何以编程方式确定是否已启用并插入NIC接口？

import subprocess

def check_nic_status():
    output = subprocess.check_output(['ifconfig'])
    output = output.decode('utf-8')  # 将字节转换为字符串
    
    interfaces = []
    current_interface = None
    
    for line in output.split('\n'):
        if line.startswith(' '):
            if current_interface is not None:
                interfaces.append(current_interface)
        else:
            if line.strip() != '':
                current_interface = line.split(':')[0]
    
    for interface in interfaces:
        status_output = subprocess.check_output(['ip', 'link', 'show', interface])
        status_output = status_output.decode('utf-8')
        
        if 'state UP' in status_output:
            mac_output = subprocess.check_output(['ip', 'link', 'show', interface])
            mac_output = mac_output.decode('utf-8')
            
            if 'NO-CARRIER' not in mac_output:
                print('Interface:', interface)
                print('Status: UP')
                # 可以进一步获取IP地址等信息
                print('IP Address:', get_ip_address(interface))
                print('---')

def get_ip_address(interface):
    output = subprocess.check_output(['ifconfig', interface])
    output = output.decode('utf-8')
    
    for line in output.split('\n'):
        if 'inet ' in line:
            return line.split('inet ')[1].split(' ')[0]
