从For循环中解析数据-批量CMD

Question

我试图写一个批处理文件，该文件创建目录并根据文件名移动图像文件（恰好是拍摄日期）。 我遇到变量设置不正确的问题。 我运行如下所示的代码，并且没有文件被移动。

@echo Off
setlocal enabledelayedexpansion
REM Collect list of file names in current directory that have the .bmp file extension. Output to text file.
dir /b "*.bmp" >BMP.txt
REM For loop examines the text file for individual file names.
FOR /F "tokens=1" %%# in (C:\Users\jhavekos\Documents\Pinger\BMP.txt) do ( 
    REM SET variable "#" to equal "token"
    Set "token=%%#&&"
    REM Extract the first 4 characters (year) from the file name and set is to variable "tokenyear"
    Set "tokenyear=%%token:~0,4%%"
    REM Extract the month characters from the file name and set the variable as "tokenmonth"
    Set "tokenmonth=%%Token:~4,2%%"
    REM Copy from current directory to: Current Directory\ImageTakenYear\ImageTakenMonth\ 
    REM Any bmps with token year and token month get copied.
    Robocopy .\ ".\%%TokenYEAR\%%TokenMonth" %%TokenYEAR%%TokenMonth*.bmp
    REM Echo the variable tokenyear
    Echo %%tokenyear
    REM Echo the variable tokenmonth
    Echo %%tokenmonth
)
pause

输出的最后一行如下所示：

%tokenmonth
%tokenyear

RoboCopy输出如下：如您所见，我需要填充变量。

   Source : C:\Users\jhavekos\Documents\Pinger\
     Dest : C:\Users\jhavekos\Documents\Pinger\%TokenYEAR\%TokenMonth%\

    Files : %TokenYEAR%TokenMonth*.bmp

  Options : /COPY:DAT /R:1000000 /W:30

我需要更改什么才能使变量成功填充？ 谢谢大家！

Answer 1

%%tokenyear不正确，并且不能扩展为可变值。 您想要％tokenyear％。 与％tokenmonth％相同。 环境变量与批处理参数或变量并不完全相同。

Answer 2

这是我最终得到的最终产品。 感谢@Squashman的帮助，已对其进行了编辑。 我还添加了将月份目录更改为月份名称的逻辑。

再次感谢！
