使用vbs删除host文件域址内容_VBS

要求：原先host里面已增加以下3行

202.102.101.105 intranet.corp
202.102.101.107 mail.intranet.corp
202.102.101.108 sip.intranet.corp

之后不需要此3行内容,所以运行以上vbs代码,来删除host文件此3行

				?

									'该脚本要求执行用户有本地管理员权限

									Const ForReading = 1, ForWriting = 2, ForAppending = 8, ReadOnly = 1

									Set fso = CreateObject("Scripting.FileSystemObject")

									Set WshShell=CreateObject("WScript.Shell")

									'WinDir 为windows安装目录

									WinDir =WshShell.ExpandEnvironmentStrings("%WinDir%")

									'设定host 文件目录

									HostsFile = WinDir & "\System32\Drivers\etc\Hosts"

									'检查host文件是否为只读，如为只读，则修改文件属性

									Set objFSO = CreateObject("Scripting.FileSystemObject")

									Set objFile = objFSO.GetFile(HostsFile)

									If objFile.Attributes And ReadOnly Then

									 objFile.Attributes = objFile.Attributes Xor ReadOnly

									End If

									Set objFSO = CreateObject("Scripting.FileSystemObject")

									Set objFile = objFSO.OpenTextFile(HostsFile, ForReading,true)

									'检查host文件里面是否已经更改过了，如果更改过，则不再执行脚本

									hostfileline=""

									Do Until objFile.AtEndOfStream

									strline = objfile.ReadLine

									If InStr (strline, "202.102.101.105") <> 0 Or (InStr (strline, "202.102.101.107"))<>0 Or (InStr (strline, "202.102.101.108"))  Then

									  strline=""

									End If

									  hostfileline=hostfileline+vbCrLf+strline

									Loop

									WScript.Echo hostfileline

									objFile.Close

									'修改host文件

									Set filetxt = fso.OpenTextFile(HostsFile, ForWriting )

									filetxt.Write hostfileline

									filetxt.Close

									WScript.Quit
