Question

我正在尝试编写一个脚本，它将ping超过600个位置的10.x.x.185，然后导出到文本文件。我知道＆gt;＆gt;可用于附加到文本文件。 IP范围如下：10.0.1.185，一直到10.50.2.185，每次递增1。我发现问题出现在10.0.255.185 ......

奖金，如果我可以在两个不同的文件中通过并失败。有什么想法吗？

Answer 1

循环可以通过两个for /L循环完成，并且管道输出到两个单独的文件有点棘手，但仍然可能。

@echo off

:: Get the vast majority of the IP addresses
for /L %%A in (0,1,49) do (
    for /L %%B in (0,1,255) do (
        (ping 10.%%A.%%B.185>nul&&echo 10.%%A.%%B.185>>success.txt)||echo 10.%%A.%%B.185>>failure.txt
    )
)

:: Get the 10.50.x.185 range separately since it only goes from 0 to 2
for /L %%A in (0,1,2) do (
    (ping 10.50.%%A.185>nul&&echo 10.50.%%A.185>>success.txt)||echo 10.50.%%A.185>>failure.txt
)

&&表示“如果先前命令成功，则仅执行此部分”，而||表示“仅在先前命令失败时才执行此操作。”

批处理文件中迭代连续数值列表的常用方法是使用for /l命令。在您的情况下，由于您需要两个不同的系列，您将需要两个嵌套的for /l循环，每个八位字节一个。

但是由于内循环的差异取决于外循环的值，我将使用环境变量来定义内循环应如何对每个外部值表现。

@echo off
    setlocal enableextensions enabledelayedexpansion

    rem Get a carriage return into a variable to later show progress in console
    for /f %%a in ('copy "%~f0" nul /z') do set "CR=%%a"

    rem Define the ranges that will be used for each of the network octets
    rem Values are those in for /l command: start step end
    set "octetA=0 1 50"
    for /l %%a in (%octetA%) do set "octetB%%a=1 1 255"
    set "octetB50=1 1 2"

    rem Iterate over the addresses. 
    rem Two streams are used to send the sucess/failure addresses to
    rem the correct log file. That way we avoid having to open/write/close
    rem each file for each write operation.

    7>"sucess.txt" 8>"failure.txt" (
        for /l %%a in (%octetA%) do for /l %%b in (!octetB%%a!) do (
            rem Show current ip being tested to console
            <nul set /p"=Testing 10.%%a.%%b.185!CR!"

            rem Execute ping command and send the address to the
            rem adecuate output stream depending on sucess/failure
            ( ping -n 1 10.%%a.%%b.185 2>nul | find "TTL=" >nul
            ) && (>&7 echo 10.%%a.%%b.185)||(>&8 echo 10.%%a.%%b.185)
        )
    )
    echo IP address testing finished
