linux沒有ifconfig後的替代命令

arp -> ip [-r] neigh
ifconfig -> ip a
netstat -> ss [-r]
route -> ip r

示例：

ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
      valid_lft forever preferred_lft forever
   inet6 ::1/128 scope host  
      valid_lft forever preferred_lft forever
2: enp4s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
   link/ether 80:fa:5b:56:48:42 brd ff:ff:ff:ff:ff:ff
3: wlp6s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
   link/ether 00:e1:8c:74:44:9c brd ff:ff:ff:ff:ff:ff
   inet 172.100.100.74/24 brd 172.100.100.255 scope global dynamic noprefixroute wlp6s0
      valid_lft 5517sec preferred_lft 5517sec
   inet6 fe80::1d02:abc1:a7ac:fb56/64 scope link noprefixroute  
      valid_lft forever preferred_lft forever

ip route  
default via 172.100.100.1 dev wlp6s0 proto dhcp metric 600  
172.100.100.0/24 dev wlp6s0 proto kernel scope link src 172.100.100.74 metric 600
