$5.$ Now we will write a shell script to display IP address of a specified interface. You know ifconfig command. Run it and check the results.

$6.$ What if you'd like to see only IP addresses? You can modify your command as

ifconfig $|$ grep 'inet $\text{'}$

grep is a command$-$line utility for searching plain$-$text data sets for lines matching a regular expression. This line means run ifconfig and return only line that starts with inet addr

$7.$ You can add interface name to ifconfig as

ifconfig eth$0|$ grep 'inet $\text{'}$

$8.$ Now we will create a script that display IP address of a specified interface. Create new file lIPscript.

echo "Choose interface $($eth$0,$ wlan$0,$ lo$)"$

read $-$e INTERFACE

echo "You chose $INTERFACE"

The first line will display input prompt, the second one accepts your input, then your input is displayed.

$9.$ Run your code and provide eth$0$ as input. If you see You chose eth$0,$ then you are ready for the next step. Provide a screenshot of your code run. $[1$ point$]$
