关于用 sed 在最后一行添加 COMMIT 字段

[qq674949301]

sed -e "s/^/-A ss_spec_wan_ac &/g" -e "1 i\-N ss_spec_wan_ac hash:net " /jffs/ignore.list
以上这段代码已经实现这样了:
-N ss_spec_wan_ac hash:net
-A ss_spec_wan_ac 0.0.0.0/8
-A ss_spec_wan_ac 10.0.0.0/8
-A ss_spec_wan_ac 100.64.0.0/10
-A ss_spec_wan_ac 127.0.0.0/8
-A ss_spec_wan_ac 169.254.0.0/16
-A ss_spec_wan_ac 172.16.0.0/12
-A ss_spec_wan_ac 192.0.0.0/24
-A ss_spec_wan_ac 192.0.2.0/24
-A ss_spec_wan_ac 192.88.99.0/24

还有我想在:"-A ss_spec_wan_ac 192.88.99.0/24"下一行添加“ COMMIT ”这个字段，如下:
-N ss_spec_wan_ac hash:net
-A ss_spec_wan_ac 0.0.0.0/8
-A ss_spec_wan_ac 10.0.0.0/8
-A ss_spec_wan_ac 100.64.0.0/10
-A ss_spec_wan_ac 127.0.0.0/8
-A ss_spec_wan_ac 169.254.0.0/16
-A ss_spec_wan_ac 172.16.0.0/12
-A ss_spec_wan_ac 192.0.0.0/24
-A ss_spec_wan_ac 192.0.2.0/24
-A ss_spec_wan_ac 192.88.99.0/24
COMMIT

我该如何修改上面这段 sed 命令来实现！

[xmoon]

&& echo COMMIT >> ignore.list

[adrianzhang]

加条命令 echo "COMMIT" >> /jffs/ignore.list

[qq674949301]

@xmoon 如果这样添加在后面会拖慢执行效率！
sed -e "s/^/-A ss_spec_wan_ac &/g" -e "1 i\-N ss_spec_wan_ac hash:net " /jffs/ignore.list && echo COMMIT >> /jffs/ipset.list
并且我的完整命令是这样的！
sed -e "s/^/-A ss_spec_wan_ac &/g" -e "1 i\-N ss_spec_wan_ac hash:net " /jffs/ignore.list | ipset -R -!

@adrianzhang
谢谢！我的完整命令是这样的，需要一整条执行下来！
