使用批处理脚本重命名上个月的文件

@echo off
setlocal

REM 获取当前日期和时间
set "current_date=%DATE%"
set "current_time=%TIME%"

REM 提取当前月份和年份
for /F "tokens=2 delims=/ " %%G in ("%current_date%") do set "current_month=%%G"
for /F "tokens=3 delims=/ " %%G in ("%current_date%") do set "current_year=%%G"

REM 计算上个月的日期
if "%current_month%"=="1" (
  set "previous_month=12"
  set /A "previous_year=current_year-1"
) else (
  set /A "previous_month=current_month-1"
  set "previous_year=current_year"
)

REM 构建重命名命令
set "old_name=%previous_year%-%previous_month%-*.txt"
set "new_name=%previous_year%-%previous_month%-renamed.txt"

REM 执行重命名命令
ren "%old_name%" "%new_name%"
