In this issue, the editor will bring you about how shell obtains the values of ip addresses. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

IpAddr=10.11.1.100

Axiom ${ipAddr%%.*}

Dumped ${ipAddr##*.}

Temp1=$ {ipAddr%.*}

Temp2=$ {ipAddr#*.}

Centering ${temp1##*.}

Baked ${temp2%%.*}

Echo "$temp1"

Echo "$temp2"

Echo "$a"

Echo "$b"

Echo "$c"

Echo "$d"

A1 = `echo $ipAddr | awk-F "[.]"'{print $1}'`

B1 = `echo $ipAddr | awk-F "[.]"'{print $2}'`

C1 = `echo $ipAddr | awk-F "[.]"'{print $3}'`

D1 = `echo $ipAddr | awk-F "[.]"'{print $4}'`

Echo "$A1"

Echo "$b1"

Echo "$C1"

Echo "$D1"

This is how the shell shared by the editor gets the values of the ip address. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
