    搞定了, 把if移到上面去就行了

1. $Hosts = "$env:windir\System32\drivers\etc\hosts"
   
2. $a = gc $Hosts
   
3. if ($a[-1] -ne '') { ac $hosts '' }
   
4. $urls = @(
   
5.         "www.baidu.com"
   
6.         "www.bing.com"
   
7. ) |
   
8. foreach{
   
9.         if ((gc $Hosts | Select-String $_) -eq $null)
   
10.         {
    
11.                 ac $hosts "127.0.0.1 $_"
    
12.         }
    
13. }

  嗯, 偶尔改手动更方便些, 改多台电脑时, 用批处理改不用到电脑旁边, 不用远程就改, 非常方便
