如果存在于For循环内

Question

我在修改了这段代码以接受多个参数后，在使其工作时遇到了麻烦。我在第二个for循环处得到"(was unexpected at this time."。(第23行)。

有没有可能在for循环里面有这些if组？根据我所看到的，这是可能的。

取代if exist组，我可以用if NOT EXPRESS来代替。我可以直接使用IF NOT EXIST，但我不知道如何让它跳过当前项的循环中的其余代码，而继续下一项的循环。我无法找到如何做到这一点，只找到了如何完全退出循环，我不想这样做。

    set /A argCount+=1
    set "argVec[!argCount!]=%%~x"
)

    set fullpath=!argVec[%%i]!
    ::get new filepath (with new extension)
    REM :names

        call %script1% !fullpath!
        set state=Processing finished
        echo %date% - %time% - !state! for !itemname! with %script1% >> %logfile%
        REM :script2
        set state=Processing started
        echo %date% - %time% - !state! for !itemname! with %script2% >> %logfile%

        echo %date% - %time% - !state! for !itemname! with %script2% >> %logfile%
        REM :log_final
        echo %date% - %time% - Plex post processing script finished for !itemname!. The file will be moved and added to the library. >> %logfile%
        echo. >> %logfile%
        REM :history_final
        echo %date% - %time% - !itemname! >> %history%
    ) else (
        echo %date% - %time% - !itemname! does not exist. Error code 1. >> %logfile%
    )
)
:end
exit /b 0

编辑：把 "if exist ( !!!fullpath!)... "中的括号去掉就可以了。

我不知道为什么最初的时候，在放入for循环里面之前，这还能用。总之，这里是最终的代码。

Answer 1

if /?

Performs conditional processing in batch programs.

IF [NOT] ERRORLEVEL number command
IF [NOT] string1==string2 command
IF [NOT] EXIST filename command

没有括号的 filename 令牌。使用

if exist !fullpath! (

甚至

if exist "!fullpath!" (
