Question

相当新的Python，请原谅基本问题和重复编码。我正在尝试编写一个PING网段的脚本，然后将结果写入几个TXT文件。

我的PING扫描部分工作得很好，我在网上找到了一些代码，但是无法将结果保存到文件中。文件已创建，但它们是空白的。

有人可以检查一下并给我一些建议吗？

import os
import os.path
import sys
import subprocess
import ipaddress

# Prompt the user to input a network address
network = input("Enter a network address in CIDR format(ex.192.168.1.0/24): ")

# Create the network
ip_net = ipaddress.ip_network(network)

# Get all hosts on that network
all_hosts = list(ip_net.hosts())

# Create output file in preset directory
os.chdir("C:\\Python364\\Output")
onlineHosts = "Online_Hosts.txt"
offlineHosts = "Offline_Hosts.txt"
on  = open(onlineHosts, 'a') # File object 'on' is created with append mode
off = open(offlineHosts, 'a') # File object 'off' is created with append mode

# Configure subprocess to hide the console window
info = subprocess.STARTUPINFO()
info.dwFlags |= subprocess.STARTF_USESHOWWINDOW
info.wShowWindow = subprocess.SW_HIDE

# For each IP address in the subnet, 
# run the ping command with subprocess.popen interface
for i in range(len(all_hosts)):
    output = subprocess.Popen(['ping', '-n', '1', '-w', '500', str(all_hosts[i])], stdout=subprocess.PIPE, startupinfo=info).communicate()[0]

    if "Destination host unreachable" in output.decode('utf-8'):
        print(str(all_hosts[i]), "is Offline")
        result = str(all_hosts[i])
        off.write(result)

    elif "Request timed out" in output.decode('utf-8'):
        print(str(all_hosts[i]), "is Offline")
        result = str(all_hosts[i])
        off.write(result)
    else:
        print(str(all_hosts[i]), "is Online")
        result = str(all_hosts[i])
        on.write(result

Answer 1

确保在完成文件后关闭文件。写作可能会留在缓冲区中，直到你这样做。

on.close（）

off.close（）

要立即写入而不关闭，您可以刷新缓冲区：

on.flush（）

off.flush（）

如果只想使用外壳，我发现以下对解决此问题很有帮助：https://ss64.com/nt/type.html

要将ping结果写入输出文件，请输入：

ping -t "SomeIPAddress" > newfile.txt

要将ping结果附加到现有输出文件中，请输入：

ping -t "some IP address" >> existingfile.txt

如果您还想在ping结果上添加时间戳，则可以在Powershell中键入以下内容：

ping -t "SomeIPAddress"|Foreach{"{0} - {1}" -f (Get-Date),$_} > > newfile.txt
