For example: The content of 1.txt is as follows
2131241
6564556
5474577

Now we need to extract the content of the first line and create a new folder with the name being the content of the first line~~~? How to solve it? Thanks~~

@echo off
for /f "tokens=2 delims=:" %%i in ('findstr /n . 1.txt^|findstr /b "1:"') do md %%i

Thanks to fastslz~~~ Every time I ask for help, someone helps, so moved...
Are there any batch processing tutorials? I also want to learn it well.

### 分析原代码及问题
#### 关于`tokens=2 delims=:`
- `tokens=2`：是指在使用`for /f`循环处理文本时，按照指定的分隔符分割后，获取第2个令牌（即分割后的第2部分内容）。
- `delims=:`：是指定分隔符为冒号`:`。这里虽然文本中可能没有分号，但这里是设置分隔符的规则。

#### 关于`('findstr /n . 1.txt^|findstr /b "1:"')`
- `findstr /n . 1.txt`：`findstr`是用于查找字符串的命令，`/n`参数表示在每一行前面加上行号，`. `表示匹配所有字符（查找1.txt文件中的所有行并带上行号）。
- `^|`：这里是转义字符，因为在命令行中`|`是管道符号，需要转义才能在`for /f`的括号内正确使用，所以`^|`表示管道符号。
- `findstr /b "1:"`：`/b`参数表示从行首开始匹配，`"1:"`表示匹配行首为`1:`的行。所以整个部分是先找出1.txt文件中所有带行号且行首为`1:`的行。

### 翻译后的内容
Is `tokens=2` to select the content of the second column of the text?
Is `delims=:` to use `:` as the delimiter? There are no semicolons in the text!
Can you explain the meaning of `('findstr /n . 1.txt^|findstr /b "1:"')`?
Thank you, waiting...

1: Content
2: Content

tokens=2 The second parameter is the content,, : is the delimiter

findstr /n is to print the line number before each matched line,, pair with 1: at the beginning of each line

I saw it in the help,, and what does ^ mean, I don't know either

那是否也可以将文本的最后一行,当作文件的名字呢
是最后一行，不是第三行;)

Is it also possible to take the last line of the text as the name of the file? It's the last line, not the third line;)

Can the last line of the text also be used as the file name?
It's the last line, not the third line ;)

The last line should be okay:
@echo off for /f "delims=" %%a in (a.txt) do set "fss=%%a" md "%fss%"
Also, the first line can be like this:
@echo off for /f "delims=" %%a in (a.txt) do if not defined fss set fss="%%a" md %fss%

Simple! Simple! Even simpler!

The first line is very clever!

```
@echo off
for /f "delims=" %%i in (a.txt) do md "%%i" &exit
```

```set/p file=<a.txt
md %file%
```

I have to admire the moderator's skills!
Can the same method be used to create a folder name for the second line?

No, this method can only get the first line of the file.

It's really powerful. I encountered a problem before.
I wanted to use findstr to find the line of text where a string appears in the file. Then read the 7th string from this line is handled like this. Let's see if there is a simpler way?

%1 is the content to be found,

@FINDSTR /i %1 log.txt >temp01.txt
FOR /F "eol=; tokens=7 delims= " %%1 in (temp01.txt) do (
Echo %%1 > temp02.txt
goto :jump1
)

:jump1

Put FINDSTR inside for
FOR /F "eol=; tokens=7 delims= " %%i in ('FINDSTR /i %1 log.txt') do Echo %%i
