在python中使用su - user执行多个命令

import subprocess

def execute_commands_as_user(commands, user):
    # 构建su命令
    su_command = ['su', '-', user, '-c']

    # 执行多个命令
    for command in commands:
        # 构建完整的命令
        full_command = su_command + [command]

        # 执行命令并获取输出
        process = subprocess.Popen(full_command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        output, error = process.communicate()

        # 打印输出结果
        print(f'Command: {command}')
        print(f'Output: {output.decode()}')
        print(f'Error: {error.decode()}')
        print('---')

# 要执行的命令列表
commands = [
    'ls',
    'pwd',
    'whoami'
]

# 执行命令作为指定用户
execute_commands_as_user(commands, 'user')
