Linux Network Card Status: How to Check if Enabled

To check if the network card is enabled in a Linux system, you can use the following methods:

1. By using the ifconfig command, you can view the status of all network interfaces in the system by typing the ifconfig command in the terminal. If the network interface is enabled, it will display information such as IP address and MAC address.
2. Use the ip command: Enter the command “ip link” in the terminal to view the status of all network devices in the system. If the network card is enabled, it will display the status of the network card as UP.
3. Check the network configuration file to confirm if the network card is enabled. The network configuration file is typically located in the /etc/network/interfaces or /etc/sysconfig/network-scripts directory. Locate the corresponding network card configuration file and review the configuration information. If the network card is configured as enabled in the file, then it is enabled.

You can easily and quickly check if the network card is enabled in the Linux system using the above methods.
