Today I'm working on the FOR statement and don't know how to combine the for statement with findstr. The following are the separate programs. Please help. Thanks~

Requirement: Extract the content after the project field

2.ini
Hierarchy ID : Normal Board
Chip SKU : 250
Project : 1060-0011
CDP : N/A

1.bat
@echo off
DEL 1.txt
findstr "^Project" 2.ini>1.txt

2.bat
@echo off
setlocal
for /f "delims=: tokens=2" %%i in (1.txt) do (
set biosv=%%i
)
echo.%biosv% >bios.dat

endlocal

Above, I want to combine 1.bat and 2.bat. How should I add 1.bat into 2.bat?

You can use statements in this style to process the result and avoid the generation of intermediate files:

FOR /F %x IN ('Command line with text output') DO ***

That command line is enclosed in single quotes, by the way, delims is best written at the end.

for /f "tokens=2 delims=: " %%i in ('findstr "^Project" 2.ini') do

Thanks~~ It has been solved~~~

Learn it! Thank you

I don't have the findstr command under DOS, and the one under WINXP can't be used. Can someone who has this tool kindly share it with me?

Is this not okay?

@echo off&setlocal enabledelayedexpansion

for /f "tokens=1* delims=:" %%i in (1.ini) do (

       set i=%%i

       if /i "!i:~0,7!"=="Project" >>bios.dat echo %%j

)

### Translation Result ###
### 对于 `for /f "tokens=1* delims=:" %%i in (1.ini) do (` 部分：
在 `for /f` 循环中，`tokens=1* delims=:` 的意思是：`tokens=1*` 表示将每行按 `delims=:` 定义的分隔符（这里是冒号）进行分割，取第一个标记赋给 `%%i`，剩下的部分赋给 `%%j`。

### 对于 `if /i "!i:~0,7!"=="Project" >>bios.dat echo %%j` 部分：
- `if /i`：表示不区分大小写进行比较。
- `!i:~0,7!`：这是字符串截取操作，`~0,7` 表示从字符串 `!i!` 的开头（索引0）开始，截取7个字符。
- 整句意思是：如果 `!i!` 这个变量从开头开始的7个字符不区分大小写等于 "Project"，就将 `%%j` 追加输出到 `bios.dat` 文件中。

So the translation of the relevant text is:

### For the part `for /f "tokens=1* delims=:" %%i in (1.ini) do (`:
In the `for /f` loop, `tokens=1* delims=:` means: `tokens=1*` means that each line is split by the delimiter defined by `delims=:` (here is the colon), the first token is assigned to `%%i`, and the remaining part is assigned to `%%j`.

### For the part `if /i "!i:~0,7!"=="Project" >>bios.dat echo %%j`:
- `if /i` means: perform a case-insensitive comparison.
- `!i:~0,7!`: this is a string intercept operation, `~0,7` means intercept 7 characters from the beginning (index 0) of the string `!i!`.
- The whole sentence means: if the 7 characters from the beginning of the `!i!` variable are case-insensitively equal to "Project", then append and output `%%j` to the `bios.dat` file.

I haven't used DOS, so I don't know if such syntax is supported under DOS. If it is supported, what does the LZ mean by researching it...

Um, okay, thanks, it can be used. Now what I don't understand is in "if /i "!i:~0,7!"=="Project" what does!i:~0,7 mean?

如果 /i "!i:~0,7!"=="Project"
/i ignore case
!i:~0,7!截取变量的前七个字符
! is the writing of % in variable delay

Thanks..Got it

Another question: The for command in pure MS-DOS doesn't seem to support the for /f statement. Can this for command be downloaded?

`for` is an internal command...

How to update the FOR command under DOS? I can't seem to find it?

```
@echo off
find /i "Project" 2.ini>han_1.txt
more +2 han_1.txt>han_2.txt
set/p k=<han_2.txt
set k=%k:*:=%
del /q han_*
echo %k:~1% >bios.dat
```
