ifconfig and ip addr in Linux CLI - Mini Project: Build & Apply

Using ifconfig and ip addr to View Network Interfaces

📖 Scenario: You are working as a system administrator and need to check the network interfaces on a Linux machine. You want to learn how to use two common commands, ifconfig and ip addr, to see details about the network interfaces.

🎯 Goal: Learn how to run ifconfig and ip addr commands to display network interface information and understand their outputs.

📋 What You'll Learn

Use the ifconfig command to list network interfaces

Use the ip addr command to list network interfaces

Understand the difference in output format between ifconfig and ip addr

Display the output of both commands clearly

💡 Why This Matters

🌍 Real World

System administrators often need to check network interfaces to troubleshoot connectivity or configure network settings.

💼 Career

Knowing how to use <code>ifconfig</code> and <code>ip addr</code> is essential for Linux system administration and network management roles.

1

Run the ifconfig command

Type the command ifconfig exactly to list all network interfaces and their details.

Linux CLI

# Type the command ifconfig below
# Your code here

Need a hint?

The ifconfig command shows network interfaces and their IP addresses.

2

Run the ip addr command

Type the command ip addr exactly to list all network interfaces and their details in a different format.

Linux CLI

ifconfig
# Type the command ip addr below
# Your code here

Need a hint?

The ip addr command is a modern alternative to ifconfig and shows more detailed info.

3

Compare the outputs of ifconfig and ip addr

Use the commands ifconfig and ip addr together to see both outputs and observe the differences.

Linux CLI

ifconfig
ip addr
# Run both commands again to compare outputs
# Your code here

Need a hint?

Use && to run ifconfig and then ip addr in one line.

4

Display the output of both commands clearly

Print the outputs of ifconfig and ip addr commands separately using echo statements to label them.

Linux CLI

ifconfig
ip addr
ifconfig && ip addr
# Add echo statements to label outputs
# Your code here

Need a hint?

Use echo to print labels before each command output.
