本文给大家分享的是使用VBS实现删除host文件里面的指定内容,非常的简单实用,有需要的小伙伴可以参考下。
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
