使用vbs删除host文件域址内容

程序员文章站 2022-06-24 15:43:26
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...

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
