5 A S dst-address=0.0.0.0/0 gateway=121.13.199.1 interface=pppoe gateway-state=reachable distance=1 scope=255 target-scope=10 routing-mark=rout_adsl

6  D  dst-address=0.0.0.0/0 gateway=121.13.199.1 interface=pppoe gateway-state=reachable distance=1 scope=30 target-scope=10


现在要删除红色的这条记录,用命令方式要怎么写?
如果是修改这条记录gateway=121.12.199.200,要用什么命令?
每条记录前面的序号能否写入一个变量中?
