- '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
复制代码 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
但是此vbs代码有些问题:
1.添加需删除的网域只能在同一行;
例如: If InStr (strline, "202.102.101.105") <> 0 Or (InStr (strline, "202.102.101.107".....
如果写成两行则vbs运行错误
vbs代码如何换下一行,才会运行成功?
2.此vbs代码运行时,会有提示画面,
如何改写代码,让它无提示画面?
3.此vbs代码运行后,开启hosts,
会发现hosts的最顶端会多出一个空白行,最尾端则多出许多空白行
此问题该如何解决? |
