@echo off ::每5分鐘復制以下首頁 for /f %%i in ('dir /b c:/index2.htm') do ( set indexdx=%%~zi ) if %indexdx% gtr 5120 ( echo y | xcopy c:/index2.htm /d /r /k c:/index.htm )
其中for /f %%i in ('dir /b c:/index2.htm') do ( set indexdx=%%~zi ) 是bat中獲取index2.htm文件大小的。
然后通過if %indexdx% gtr 5120 ( 實現判斷是不是大于5120個字節
主要就是下面這個代碼了功能更強，也比較簡單
復制代碼 代碼如下:
Dim fso Set fso = CreateObject("Scripting.FileSystemObject") set fn2=fso.GetFile("c:/index2.htm") flsize2=fn2.size fldate2=fn2.datelastmodified set fn=fso.GetFile("c:/index.htm") flsize1=fn.size fldate1=fn.datelastmodified If fso.FileExists("c:/index2.htm") and flsize2>50000 and fldate2>fldate1 Then fso.getfile("c:/index2.htm").copy("c:/index.htm") if err.number=0 then WriteHistory "成功"&now(),"log.txt" end if
Sub WriteHistory(hisChars, path) Const ForReading = 1, ForAppending = 8 Dim fso, f Set fso = CreateObject("Scripting.FileSystemObject") Set f = fso.OpenTextFile(path, ForAppending, True) f.WriteLine hisChars f.Close End Sub
