批处理脚本循环& NSLOOKUP [英] Batch script for loop & nslookup

问题描述

我之前看过这个问题，但没有解决我的问题。我只是试图遍历包含主机名的文本文件。当我从命令行尝试相同的命令（省略额外的百分号）时，它将工作一两次然后给出下面指出的错误。将其作为批处理文件运行，批处理文件将不做任何事情而退出。

以下是批处理文件中的代码：

  @echo off 
 set OUTPUTFILE = Results / Results.txt 
 set lookup = HostNames.txt 
 FOR / F %% i in（％lookup％）do 
 FOR / Fusebackq skip = 3 delims =：tokens = 2％j in（`nslookup％i`）
 do @echo %% i %% j>> ％OUTPUTFILE％
  

在命令行中，我得到：

）在这个时候是意外的。

当我在一个命令当我在批处理文件中运行时，我正在取出额外的百分号。我也在命令行中使用绝对路径，以确保它不是我设置的环境变量的问题。

解决方案 $> $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ in（％lookup％）do（
FOR / Fskip = 3 delims =：tokens = 2%% j in（'echo（^ | nslookup %% i'）do @echo %% i %% j>>％OUTPUTFILE％
）

问题：
/ 是winbatch中的一个开关; \ 是一个目录级别分隔符。

do（必须与在同一实体行上

％i 应该是 %% i

％j 应该是 %% j

我已经删除了 usebackq ，并将引号从反引号改为了单引号，因为它没有必要使用 usebackq here。

（添加了一些小修正）

闪烁的光标是由 nslookup 从键盘请求信息。添加 echo（提供换行符来终止 nslookup 和 ^ | 是一个将 echo 的输出指向 nslookup 的输入的转义管道。 b
$ b

由于我的设置与您的设置有很大的不同，我只能做原始验证。


I've seen this question posted before, but none of the solutions address my issue. I'm simply trying to iterate through a text file that contains host names. When I try the same command (omitting the extra percent signs) from the command line, it will work once or twice then then give the error noted below. Running it as a batch file, the batch file exits without doing anything. This one has really stumped me.

Here's the code in my batch file:

@echo off
set OUTPUTFILE=Results/Results.txt
set lookup=HostNames.txt
FOR /F %%i in (%lookup%) do 
FOR /F "usebackq skip=3 delims=: tokens=2" %j in (`nslookup %i`) 
do @echo %%i %%j >> %OUTPUTFILE%

At a command line I get:

i`) was unexpected at this time.

When I run it at a command line I am taking out the additional percent signs needs when it runs in a batch file. I'm also using absolute paths at the command line, to ensure it this isn't an issue with the environment variables I've set.

解决方案

@echo off
set OUTPUTFILE=Results\Results.txt
set lookup=HostNames.txt
FOR /F %%i in (%lookup%) do ( 
 FOR /F "skip=3 delims=: tokens=2" %%j in ('echo(^|nslookup %%i') do @echo %%i %%j >> %OUTPUTFILE%
)

Problems: / is a switch in winbatch; \ is a directory-level-separator.

do ( must be on the same physical line as its for

%i should be %%i

%j should be %%j

I've removed the usebackq and changed the quotes from backticks to single-quotes as it's not necessary to use usebackq here.

(minor fixes added)

The "flashing cursor" is caused by nslookup requesting information from the keyboard. Adding echo( supplies a newline to terminate nslookup and ^| is an escaped-pipe which directs the output of that echo to the input of nslookup.

Since my setup differs radically from yours, I can do but primitive verification.
