Windows批处理文件嵌套的For循环

Question

这个人有中年危机。我有一个txt文件，其中包含文件和文件大小的列表，我正在遍历该文件，并将其与磁盘上实际找到的文件进行比较。文件列表是另一台服务器上的远程文件。

数据：

代码：

@ECHO OFF

SET TestDir=S:\Documents\testplatform\data\
@ECHO Checking %TestDir%    
    
SETLOCAL EnableDelayedExpansion

SET ActualSize=0

for /F "tokens=1,2 delims=|" %%i in (%TestDir%\files.txt) do (

    for %%A in (%TestDir%%%i) do (
        set ActualSize=%%~zA
    )

    @ECHO File: %%i, Server Size: %%j, ActualSize: !ActualSize!
)

PAUSE
SETLOCAL DisableDelayedExpansion

问题是，无论我如何尝试使用%%或!!，我都无法让ActualSize显示实际大小。我知道这与设置ActualSize=%%~zA在批处理文件中没有正确的作用域有关。

任何帮助都将不胜感激。

Answer 1

:: get the filesize of each file and save it in ActualSize是非法语句。删除它或将其转换为注释备注(也称为)- REM get the filesize of each file and save it in ActualSize。

你正在张贴你发现的非法代码，并询问为什么非法代码不起作用。，因为它是非法的。

:是一个Goto目标，在Windows命令行界面中称为label。

键入rem /?和goto /?。

Answer 2

工作代码：

@ECHO OFF

SET TestDir=S:\Documents\testplatform\data\
SET MaxDifference=256
@ECHO Checking %TestDir%

    
SETLOCAL EnableDelayedExpansion

SET ActualSize=0

:: loop over the test data file
for /F "tokens=1,2 delims=|" %%i in (%TestDir%\files.txt) do (

    :: get the filesize of each file and save it in ActualSize
    for %%A in (%TestDir%%%i) do (
        SET /A ActualSize=0
    SET /A ActualSize=%%~zA
    )

    
    SET /A Difference=!ActualSize!-%%j
    IF !Difference! LSS 0 SET /A Difference=!Difference!*-1
    IF !Difference! GTR !MaxDifference! (
        @ECHO File: %%i, Server Size: %%j, ActualSize: !ActualSize!, Difference: !Difference!
    )
)
SETLOCAL DisableDelayedExpansion

PAUSE

输出：

Checking S:\Documents\testplatform\data\
File: /playlist-1.html, Server Size: 6360, ActualSize: 6581, Difference: 221
File: /playlist-2.html, Server Size: 6340, ActualSize: 6561, Difference: 221
File: /playlist-3.html, Server Size: 6396, ActualSize: 6617, Difference: 221
