如果计数for达到j，我将不离开0循环。

set /a j=3
for /R c:\dsd_imports\ad_and_deal %%i IN (*.*) DO (
  MDI_import_ad_command.bat C:\DSD_IMPORTS\AD_AND_DEAL\%%~nxi
  MOVE %%i c:\dsd_imports\ad_and_deal\in_process
  set /a j=j-1
  if j == 0
     break
)

最佳答案

这是您的批处理代码重写和注释:

@echo off
rem Define environment variable FileCount with value 3.
set "FileCount=3"

rem Push path of current directory on stack and make specified directory
rem the current directory for everything up to command POPD.
pushd C:\dsd_imports\ad_and_deal

rem Process in directory specified above all non hidden files.

rem For each file call another batch file with name of current file.
rem Then move current file to subdirectory in_process and decrement
rem the file count variable by 1.

rem Enable delayed expansion which results also in creating a copy of
rem all environment variables and pushing current directory once again
rem on stack.

rem Run a string comparison (a few microseconds faster than an integer
rem comparison as environment variables are always of type string) to
rem determine if 3 files were already processed in which case the loop
rem is exited with a jump to a label below the loop.

rem In any case the previous environment must be restored with command
rem ENDLOCAL before the batch file execution continues on label Done or
rem with loop execution.

for %%I in (*) do (
    call MDI_import_ad_command.bat "%%I"
    move /Y "%%I" in_process\
    set /A FileCount-=1
    setlocal EnableDelayedExpansion
    if "!FileCount!" == "0" endlocal & goto Done
    endlocal
)

rem Delete the environment variable FileCount as no longer needed.
rem Then pop the previous current directory path from stack and make
rem this directory again the current directory for rest of batch file.

:Done
set "FileCount="
