Shell obtains the IP address of the local machine.

If you have multiple NICs, you must specify the NIC name because the IP address is related to the NIC.

The method for getting the IP address of the specified Nic is:

 

Ifconfig eth0 | sed-n "p" | awk '{print substr ($ )}'

 

"Eth0" indicates the name of the network card you specified.

Sed-n "p" indicates the second row in the result.

Awk '{print substr ($ 6th)}' indicates the string starting with characters in the second item, that is, the part starting with the IP address string.

 

 

The output result is shown as follows:

192.168.1.8
