'exist' 返回 true，但其他命令如 `fc` 找不到文件

Question

if exist "./snapshots/!filename!.txt"

为真，因此进入子句， 但

fc

（和其他命令）无论如何都找不到该文件，打印出：

FC: cannot open ./SNAPSHOTS/*filename*.TXT - No such file or folder

@echo off
setlocal enabledelayedexpansion

set passed=0
set failed=0
set nosnaps=0

for %%i in (./tests/*) do (
    set "filename=%%~ni"
    
    dune exec ../_build/default/bin/main.exe ./tests/%%i > "./results/!filename!.txt" 2> nul
    
    if exist "./snapshots/!filename!.txt" (

        fc "./snapshots/!filename!.txt" "./results/!filename!.txt" > nul
        if !errorlevel! == 0 (
            echo PASSED TEST: !filename!
            set /a passed+=1
        ) else (
            echo FAILED TEST: !filename!
            set /a failed+=1
        )
    ) else (
        echo NOSNAP TEST: !filename!
        set /a nosnaps+=1
    )
)

echo --------
echo PASSED: !passed!
echo FAILED: !failed!
echo NOSNAP: !nosnaps!

endlocal

虽然这可能无法解决您的问题，但它使用正确的语法。它还不会不必要地使用延迟扩展，或定义和使用不必要的变量。

@Echo Off
SetLocal EnableExtensions DisableDelayedExpansion

Set /A passed=failed=nosnaps=0

For %%G In ("tests\*") Do (
    
    dune.exe exec ../_build/default/bin/main.exe "./tests/%%G" 1>"results\%%~nG.txt" 2>NUL
    
    If Exist "snapshots\%%~nG.txt" (
        %SystemRoot%\System32\fc.exe "snapshots/%%~nG.txt" "results\%%~nG.txt" 1>NUL && (
            Echo PASSED TEST: %%~nG
            Set /A passed += 1
        ) || (
            Echo FAILED TEST: %%~nG
            Set /A failed += 1
        )
    ) Else (
        Echo NOSNAP TEST: %%~nG
        Set /A nosnaps += 1
    )
)

Echo --------
Echo PASSED: %passed%
Echo FAILED: %failed%
Echo NOSNAP: %nosnaps%

EndLocal

如果

"./tests/%%G"

.exe 不是为 Windows 操作系统引用语法设计的，您可能需要将

'./tests/%%G'

更改为

dune

。
