請教下這個批處理的意思@if(0)==(0) echo offtitle 中共打碼文件備份 by Jrem 獲取當前set d=%date:~0,4%%date:~5,2%%date:~8,2%rem 中共打碼文件路徑rem 判斷路徑for /f delims= %%i in ('cscript -nologo -e:jscript %~f0') do (echo %%irem)rem echo 完成時間:>>D:scan_logDamajietuFiles_log.txtrem date /t>>D:scan_logDamajietuFiles_log.txt && time /t>>D:scan_logDamajietuFiles_log.txtremecho ------------------------------------------------->>D:scan_logDamajietuFiles_log.txtpauseremexit /b & @endfor(var i=1;i<=30;i++) {var now = new Date();now.setDate(now.getDate() - i);var y = now.getFullYear();var m = now.getMonth();var d = now.getDate();var m = m+1<10 ? 0 + (m + 1) : m + 1;var d = d<10 ? 0 + d : d;WSH.Echo(y++m++d);}麻煩問下，@if(0)==(0)腳本中這個是什么意思，還有這個調用的時候的解釋。
