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
