如何在python脚本中运行linux (ubuntu)命令？

import subprocess

def run_linux_command(command):
    try:
        # 执行命令并获取输出
        output = subprocess.check_output(command, shell=True, stderr=subprocess.STDOUT)
        # 将输出转换为字符串并去除末尾的换行符
        output = output.decode().rstrip('\n')
        return output
    except subprocess.CalledProcessError as e:
        # 如果命令执行失败，可以在这里处理异常
        print(f"Command '{command}' failed with error code {e.returncode}: {e.output.decode()}")
        return None

# 示例：运行'ls'命令并打印输出
result = run_linux_command('ls')
print(result)
