Batch process add multiple new domain names to Hosts_dos/bat

Requirements: Batch (. bat) add more than one new domain name to hosts, first detect if the existing domain name is not added

Other domain names that do not already exist, add directly

Google search is there to find the code as follows:

Copy Code code as follows:

Set sthosts= x.x.x.x www.domainname.com
for/f "eol=# Tokens=1 delims="%%i in (%systemroot%\system32\drivers\etc\hosts) do if "%sthosts%" = "%%i" exit
Echo%sthosts%>>%systemroot%\system32\drivers\etc\hosts

However, this code can only detect one row of domain names

How can you rewrite code to detect multiple domain names if you want to add the following various domain addresses?

127.0.0.1 mcfg.sandai.net
127.0.0.1 211.94.190.80
127.0.0.1 advstat.xunlei.com
123.87.86.5 biz5.sandai.net

Method One:

@echo off & setlocal enabledelayedexpansion
Set "file=%systemroot%\system32\drivers\etc\hosts"
for/f " Tokens=2 "%%i in (' More +11"%~0 ") do set #%%i=1
for/f" delims= "%%i in (' findstr/n. *%file% ') do (
  set) s=%%i "
  Set" s=!s:*:=! "
  for/f "tokens=1,2"%%j in ("#!s!") does if not defined #%%k s!
)
More +11 "%~0"
Pause & Exit

Method Two: With the detection function (various domain addresses are written in a file named List.txt, one line)

@echo off
if exist%temp%\$ del/q%temp%\$
for/f ' delims= '%%i in (%systemroot%\system32\drivers\etc\hosts) do E Cho%%i>>%temp%\$
for/f "delims="%%a in (' findstr/v/g: "%temp%\$" List.txt ") do echo%%a>>%systemroot% \system32\drivers\etc\hosts
