问题 I am using pexpect to upload a file to SFTP server. For accesssing the server first time, I get message as The authenticity of host..can't be established.Are you sure you want to continue connecting (yes/no)? to which I want the user to interact and answer yes/no. However, when user says yes, I want the interactive mode to be off and then take the password from my script instead of prompting user. Is this possible using pexpect ? p = spawn('XXXXXXXX') password = 'XXXXXXXXx' out=p.expect(['(?i

问题 Rust's std::process::Command allows configuring the process' stdin via the stdin method, but it appears that that method only accepts existing files or pipes. Given a slice of bytes, how would you go about writing it to the stdin of a Command ? 回答1: You can create a stdin pipe and write the bytes on it. As Command::output immediately closes the stdin, you'll have to use Command::spawn . Command::spawn inherits stdin by default. You'll have to use Command::stdin to change the behavior. Here is

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed yesterday . Improve this question I would like to run the following commands in Python, using the package subprocess. cd C:\Users\...\csv attrib +U -P /s In my mind, I would like to do something like cmd = [r'C:\Users\...\csv','attrib +U -P /s'] pro = subprocess.Popen(cmd, stdout=subprocess

问题 I'm trying to use python Subprocess module to enable/disable Ethernet connection from python code. Below is my code in which the first step is looking for the available "Ethernet Connections" and the next step enables/disables the ethernet connection according to the parameter passed in "%interfaces%". for /f "skip=2 tokens=3*" %%A in ('netsh interface show interface') do set interface=%%B netsh interface set interface %interface% ENABLED Now when using in python I couldn't pass the variable,

问题 I'm trying to get the standard output of a bash command as a string in Python. Following Popen documentation, I've tried: import subprocess p = subprocess.Popen(["echo", "hello"]) stdoutdata, stderrdata = p.communicate() print stdoutdata Running this script yields the following output: hello None [Finished in 0.0s] So although the output is getting printed by Python, the stdoutdata variable is None , and not "hello" as I would like. How can I make it so? 回答1: You're not providing any stdout
