问题描述
我想在 Ubuntu 上使用 Python 脚本对新的空白磁盘进行分区.
I want to partition a new, blank disk using a Python script on Ubuntu.
在 bash 脚本或命令行中，这将完成这项工作:
In a bash script or from the command line, this would do the job:
$echo -e "n\np\n1\n\n\nw\n" | sudo fdisk /dev/X
其中 X 是有问题的 HDD.
where X is the HDD in question.
我尝试使用 subprocess 模块将其移植到 Python 脚本中，如下所示:
I have tried to port this into a Python script using the subprocess module, as follows:
p = subprocess.Popen(cmdString, stdout=subprocess.PIPE, \
close_fds=False, stderr=subprocess.PIPE,shell=True)
stdoutAndErr = p.communicate()
其中 cmdString 与上面的 "echo -e ..." 字符串相同.
where cmdString is just the same "echo -e ..." string above.
虽然这行不通.输出只是 fdisk 打印出命令选项，所以它显然不喜欢我发送的内容.
This doesn't work though. Output is just fdisk printing out the command options, so it clearly doesn't like what I am sending it.
上述简单的生活方式有什么问题?
What's wrong with the above simple approach to life?
