awk - 关于 sed awk grep 的使用

Question

大家，我应该用什么命令行来实现这个效果呢？

这是尝试使用 awk 和 sed 但失败了。请指教。

Original:
server=/example-a.com/127.0.0.1#5353
ipset=/example-a.com/router
server=/example-b.com/127.0.0.1#5353
ipset=/example-b.com/router
server=/example-c.com/127.0.0.1#5353
ipset=/example-c.com/router

Achieve effect:
server=/example-a.com/127.0.0.1#5353
server=/example-a.com/127.0.0.2#5354
ipset=/example-a.com/router
server=/example-b.com/127.0.0.1#5353
server=/example-b.com/127.0.0.2#5354
ipset=/example-b.com/router
server=/example-c.com/127.0.0.1#5353
server=/example-c.com/127.0.0.2#5354
ipset=/example-c.com/router

既然你需要算术，我会选择awk：

awk -F'[#.]' '/^server/ { print $0, ORS $1"."$2"."$3"."$4"."$5+1"#"$6+1 } !/^server/'

输出：

server=/example-a.com/127.0.0.1#5353 
server=/example-a.com/127.0.0.2#5354
ipset=/example-a.com/router
server=/example-b.com/127.0.0.1#5353 
server=/example-b.com/127.0.0.2#5354
ipset=/example-b.com/router
server=/example-c.com/127.0.0.1#5353 
server=/example-c.com/127.0.0.2#5354
ipset=/example-c.com/router
