我正在编写一个批处理脚本，通过 ftp 将预定义文件夹的每个子文件夹传输到远程服务器。

一切正常，但在for循环中，它只执行一次，只传输一个文件夹，然后跳出循环。

我在for循环中有一堆代码

FOR /f "delims= " %%B IN ('DIR "%backup_dir%" /A:D /B') DO (

    here is my code

)

当我在 for 循环中使用一些短代码(如“echo”)时，它会正确运行。但是当我用 ftp 命令放置一堆代码时却不是。这些 ftp 代码可以正确运行但只能运行一次，然后它会打破循环。

下面是for循环中的一段代码

    REM -- Send most recent daily backups offsite
IF !daily_flag! EQU YES (
    ECHO -- Starting Daily backups for !current_folder!
    ECHO.
    CD 1DAYS_OLD\

    REM -- Start entries for ftp commands file
    ECHO user %login% %pass% > %ftp_cmds1%
    ECHO cd backup/files/!current_folder!/1DAYS_OLD >> %ftp_cmds1%
    ECHO quit >> %ftp_cmds1%

    SET go_flag=NO
    SET /a ftp_cntr=0
    REM -- Loop to see if offsite backup server is alive
    :CHECK_FTP1
    IF !go_flag! EQU NO (
        ECHO %ftp_cmds1% > %ftp_dbg1%
        ftp -ind -s:%ftp_cmds1% %machine_ip% > %ftp_dbg1%

        REM -- Check ftp debug file to decide what to do
        FIND /i "Not connected" %ftp_dbg1%
        IF !ERRORLEVEL! EQU 0 (
            ECHO *** Unable to connect to offsite backup machine: %machine_ip% at %DATE%
            ECHO !ftp_cntr!
            IF !ftp_cntr! GTR 10 (
                ECHO *** Unable to connect to offsite backup machine: %machine_ip% for 10 minutes from %machine%
                ECHO ----- Start ftp debug file
                TYPE %ftp_dbg1%
                ECHO ----- End ftp debug file

                DEL /f /q %ftp_cmds1%
                DEL /f /q %ftp_dbg1%
                EXIT 2
            ) ELSE (
                TIMEOUT /t 60
                SET /a ftp_cntr+= 1
            )
        ) ELSE (
            SET go_flag=YES
            ECHO Offsite backup machine is alive, proceeding with ftp
        )
        GOTO :CHECK_FTP1
    )

    FIND /i "No such file or directory" %ftp_dbg1%
    IF !ERRORLEVEL! EQU 0 (
        ECHO * Directory backup/files/!current_folder! does not exist on offsite backup machine.
        SET go_flag=MKDIR
    )

    REM -- IF %go_flag% == MKDIR create remote directory structure

如果您在其中执行任何 GOTO，FOR 命令将被取消。为了解决这个问题，在 FOR 命令中调用一个子程序，并在子程序中执行任何你想要的过程(包括 goto 的)。
