求助，怎么从一个文件中提取一些字符并输出？
就好像我ping网关，怎么把丢包率%0 loss输出来？谢谢各位呀，急呀！

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 2ms, Average = 1ms

是不是这样？

for /f "delims=() tokens=2" %i in ('"ping 192.168.1.1 | find "Packets""') do echo %i

for /f "delims=(l tokens=2" %i in ('"ping 192.168.1.1 | find "Packets""') do echo %i

命令行中执行，批处理中需用%%i来代替%i

在WIN2000以上系统中可以使用:

for /f "usebackq tokens=2 delims=()" %i in (`ping 192.168.1.1^|find /i "loss)"`) do echo %i

学习了!

for /f "tokens=2 delims=()" %i in ('ping 192.168.1.1^|find /i "loss)"') do echo %i
