ip -o -4 addr show up primary scope global | grep -E '10.254|10.144' | awk '{print $2,$4}'

輸出結(jié)果可能像下面這樣

[root@xxx ~]# ip -o -4 addr show up primary scope global | awk '{print $2,$4}'
bond0 10.254.5.45/24
bond1.768 10.141.0.243/24
bond1.769 10.141.1.243/24
virbr0 192.168.122.1/24
docker0 172.17.0.1/16

• -o uses the one-line output format, which is easier to process with read, grep, etc.

• -4 for IPV4 address

• up excludes devices that aren't active

• scope global excludes private/local addresses such as 127.0.0.1 and fe80::/64

• primary excludes temporary addresses (assuming you want an address that doesn't change)

• 支持多塊網(wǎng)卡設(shè)備
