令牌数的限制命令在Windows批处理脚本 [英] Number of tokens limit in a FOR command in a Windows batch script

问题描述

我试图来处理在Windows批处理脚本的文本文件，我碰到了东西，看起来像一个限制31令牌在for循环中。我将问题在下面的code：

I was trying to process a text file in a Windows batch script and I ran into something that looks like a limitation to 31 tokens in a FOR loop. I isolated the issue in the code below:

@ECHO OFF
SET DATA=01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

FOR /F "tokens=31* delims= " %%i IN ("%DATA%") DO (
    ECHO [%%i]
    ECHO [%%j]
)
ECHO.
FOR /F "tokens=32* delims= " %%i IN ("%DATA%") DO (
    ECHO [%%i]
    ECHO [%%j]
)

输出是：

[31]
[32 33 34 35]

[01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35]
[%j]

和我期待这样的：

[31]
[32 33 34 35]

[32]
[33 34 35]

希望我没有做错事，我找不到这个限制在帮助文档的FOR命令。我使用Windows XP。你从斩去零件的数据，知道该什么解决办法，除了？

Hoping that I haven't been doing something wrong, I couldn't find this limitation documented in the help for the FOR command. I'm using Windows XP. Do you know any workaround for this, aside from chopping off parts of the data?

感谢您。

推荐答案

我想出了一个解决方案。这不是优雅，但它解决了我的问题。
当条命令行间preTER不能与令牌走得更远，我传递数据的，其剩余的一个CALL：标签命令。下面是一个例子：

I came up with a solution. It's not elegant, but it solves my problem. When the commmand line interpreter cannot go further with the tokens, I pass the remaning of the data to a CALL :label command. Here is an example:

@ECHO OFF

SET DATA=01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100

FOR /F "tokens=1,31* delims= " %%i IN ("%DATA%") DO (
    ECHO  1st token: %%i
    ECHO 31th token: %%j
    CALL :processdatatokens32-62 %%k
)

:processdatatokens32-62
SET DATA=%*
FOR /F "tokens=1,31* delims= " %%i IN ("%DATA%") DO (
    ECHO 32nd token: %%i
    ECHO 62th token: %%j
    CALL :processdatatokens63-83 %%k
)
GOTO :EOF

:processdatatokens63-83
SET DATA=%*
FOR /F "tokens=1,31* delims= " %%i IN ("%DATA%") DO (
    ECHO 63th token: %%i
    ECHO 93th token: %%j
)
GOTO :EOF

输出是：

 1st token: 01
31th token: 31
32nd token: 32
62th token: 62
63th token: 63
93th token: 93
