How To: Linux Show List Of Network Cards

You can use the ip or ifconfig command to show a list of network cards on a Linux system.

Here's how you can use the ip command:

1. Open a terminal window.

2. Run the following command: ip link show.

3. The output will show a list of network interfaces, each with a unique identifier in the form <interface_name>:. For example:

 

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000

Here's how you can use the ifconfig command:

1. Open a terminal window.

2. Run the following command: ifconfig.

3. The output will show a list of network interfaces, each with its own section. For example:
