微軟帝國 : [分享] DOS 批次檔 batch file 取得日期為變數值的運用

 @echo off
 @For /f "tokens=1-3 delims=/" %%a in ('date /t') do (set date=%%a-%%b-%%c)
 @For /f "tokens=2-3 delims=:" %%a in ('time /t') do (set time=%%a:%%b)

 REM 這個 %date% 或 %time% 變數可以拿來做很多用途...
 @echo The date is %date%
 @echo The time is %time%

 REM 產生每天的資料夾 (如果目錄不存在就建立目錄)
 @IF NOT EXIST %date% mkdir %date%

 REM **********************************
 REM 以任何方式檢查伺服器的狀態....
 REM **********************************

 REM 產生每天的 log 檔名，並記錄時間 (如果檔案不存在就建立檔案)
 @set dailylog=%date%.log
 @IF NOT EXIST %date%/%dailylog% echo ******************** > %date%/%dailylog%

 REM 如果伺服器掛掉了，就記錄下來
 @echo %date% %time% >> %date%/%dailylog%
 @echo Mail Server is Down >> %date%/%dailylog%
 echo ******************** >> %date%/%dailylog%

 REM 這裏是暫停命令提示字元視窗
 pause

@ECHO OFF
@For /f "tokens=1-3 delims=/ " %%a in ('date /t') do (set date=%%a-%%b-%%c) 
@echo The date is %date% 

@set log={產出路徑}\{產出檔名}.log
@echo %date% %time% >> %log%
echo **************************************** >> %log%

"C:\Program Files\WinRAR\rar.exe" a -df -ed -m5 -r -s -tk "D:\BackupShell\Backup_%date%.rar" "{備份路徑}\{要備份的檔案}" >> %log%
