[已解决]BAT如何控制ping批量运行？

pZjVa0

p.bat↓

1. @echo off
   
2. for /f %%a in (ip.txt) do start /b ping %%a
   
3. pause

复制代码

ip.txt↓

1. 192.168.1.1
   
2. 192.168.1.2
   
3. 192.168.1.3
   
4. 192.168.1.4
   
5. 192.168.1.5
   
6. 192.168.1.11
   
7. 192.168.1.12
   
8. 192.168.1.13
   
9. 192.168.1.8
   
10. 192.168.1.9
    
11. 192.168.1.11
    
12. 192.168.1.12

以上面为例，读取ip.txt中每行ip并用start打开进行ping。但如果要判断当读取到文本的最后一段ping时，则不使用start运行，而是直接ping 最后一行的192.168.1.12，应该如何实现?谢谢

效果示意:

1. start ping 192.168.1.1
   
2. start ping 192.168.1.2
   
3. start ping 192.168.1.3
   
4. start ping 192.168.1.4
   
5. start ping 192.168.1.5
   
6. start ping 192.168.1.11
   
7. start ping 192.168.1.12
   
8. start ping 192.168.1.13
   
9. start ping 192.168.1.8
   
10. start ping 192.168.1.9
    
11. start ping 192.168.1.11
    
12. ping 192.168.1.12
