将文件夹重命名为当前月份-3的Windows命令行脚本(例如2009-04到2009-01)

对于我所在的地区,我需要一些不同的东西。

setlocal
@REM example:  Thu 06-11-2009
set stamp=%DATE%

@REM get the year
set year=%stamp:~10,4%
@REM example: 2009

@REM get the month
set month=%stamp:~4,2%
@REM example:  06

@REM subtract 3 months
set /a month=%month%-3
@REM example:  3

@REM test if negative (we rolled back beyond January 1st)
if %month% LSS 1  (
  set /a month=%month%+12
  @REM example: 8
  set /a year=%year%-1
  @REM example: 2008
)

@REM prepend with zero for single-digit month numbers
set month=0%month%

@REM take last 2 digits of THAT
set month=%month:~-2%

set newFolder=%year%-%month%

@REM move %1 %newFolder%
endlocal

你必须剖析 %DATE% 不幸的是,你一个人。cmd中没有本地化安全的日期/时间操作工具。

@echo off
rem %DATE% comes back in ISO 8601 format here, that is, YYYY-MM-DD
set Y=%DATE:~0,4%
set /a M=%DATE:~5,2% - 3
if %M% LSS 1 (
    set /a Y-=1
    set /a M+=12
)
ren myFolder "%Y%-%M%"
