从批处理脚本文本文件中读取特定的Word（2号线，3字） [英] Read specific Word(Line 2, Word 3) from a text file by batch script

问题描述

我需要从通过​​批处理脚本文本文件中读取特定的单词。说我要行2字3被读取。

下面是code：

  @ECHO OFF
    CLS
    SET /普线=请输入行号：
    进入ECHO行号：％行％    SET / p字=请输入字数：
    进入ECHO字号码是：％字％
    FOR / F令牌=％字％跳跃=％行％delims =%% G IN（E_dir.txt）DO呼应选的词是：%%摹
 

问题是，这给了我所有的话3号线从2开始（例如，用户输入的是1号线，3字）。有一个与行数有问题，但是我可以搞定。我的问题是它给我所有的话时，我只需要2号线的单个字和字3。

输入文件： E_Dir.txt

二月，多雨，15
三月，阳光明媚，25
四月，测试20

 请输入号码：1
进入行号：1
请输入字数：3
进入字编号为：3
选择的字是：15
选择的字是：25
选择的字是：20
 

期望输出：

 请输入号码：1
进入行号：1
请输入字数：3
进入字编号为：3
选择的字是：15
 

解决方案

路第一
...

  FOR / F令牌=％字％跳跃=％行％delims =%% G IN（E_dir.txt）DO呼应选的词是：%% G＆安培;转到nextline
：nextline
 

办法第二
...

 集SHOWME = Y
FOR / F令牌=％字％跳跃=％行％delims =%% G IN（E_dir.txt）做，如果定义设置SHOWME SHOWME =安培;回声选上的话就是：%%摹
 

---

修改

  SET / A SHOWME =行1
SET SHOWME =跳过=％SHOWME％
IF％行％EQU 1套SHOWME =
FOR / F令牌=％字％SHOWME％％delims =%% G IN（E_dir.txt）做，如果定义设置SHOWME SHOWME =安培;回声选上的话就是：%%摹
 

请注意，这里的％行％ 1 SHOWME 是故意设置的空间。这确保了 SHOWME 具有价值进行初始。

我不知道你在哪里流浪2的来源。该程序为我工作。也许你可能想用十六进制编辑器查看的资源文件。它可以具有没有低频的线。也可能检查您的批次。如果你已经使用记事本，尝试像EDITPLUS或记事本编辑+ +。记事本做一些奇怪的事情。

I need to read specific words from a text file through batch script. Say I want Line 2 word 3 to be read.

Here is the code::

   @ECHO OFF
    cls
    SET /P line=Please enter Line number: 
    ECHO Line number entered is : %line%

    SET /P word=Please enter Word number: 
    ECHO Word number entered is : %word%


    FOR /F "tokens=%word% skip=%line% delims=," %%G IN (E_dir.txt) DO echo Chosen word is: %%G

The problem is, this gives me all the 3rd words starting from line 2. (say, user input is line 1, Word 3). There is a problem with the line count, But I can handle that. My problem is it is giving me all the words when I need only the single word of Line 2 and word 3.

Input file: E_Dir.txt

January,Snowy,02
February,Rainy,15
March,Sunny,25
April,Test,20

Output:

Please enter Line number: 1
Line number entered is : 1
Please enter Word number: 3
Word number entered is : 3
Chosen word is: 15
Chosen word is: 25
Chosen word is: 20

Expected Output:

Please enter Line number: 1
Line number entered is : 1
Please enter Word number: 3
Word number entered is : 3
Chosen word is: 15

解决方案

Way the first ...

FOR /F "tokens=%word% skip=%line% delims=," %%G IN (E_dir.txt) DO echo Chosen word is: %%G&goto nextline
:nextline

Way the second ...

set showme=Y
FOR /F "tokens=%word% skip=%line% delims=," %%G IN (E_dir.txt) DO if defined showme set showme=&echo Chosen word is: %%G

---

Amendment

SET /a showme=line-1
SET showme=skip=%showme%
IF %line% equ 1 set "showme= "
FOR /F "tokens=%word% %showme% delims=," %%G IN (E_dir.txt) DO if defined showme set showme=&echo Chosen word is: %%G

Note that where %line% is 1, showme is deliberately set to a SPACE. This ensures that showme has a value initially.

I have no idea where your stray "2" is coming from. The procedure worked for me. Perhaps you may want to check the sourcefile with a hex editor. It may have a line without a LF. Possibly also check your batch. If you've used NOTEPAD, try an editor like EDITPLUS or NOTEPAD++. Notepad does some strange things.
