ifconfig:tldr:5e291
The command "ifconfig eth0 ${ip_address}" is used to configure the network interface card (NIC) eth0 with a specific IP address.
Here's a breakdown of each component:
-
"ifconfig": This is a command-line utility used to configure network interfaces on Unix-like operating systems. It allows administrators to view and modify network interface parameters, including IP addresses, netmask, and other configurations.
-
"eth0": The "eth0" specifies the network interface on which the command will operate. In this case, it is referring to the first Ethernet interface on the system.
-
"${ip_address}": This is a placeholder for the actual IP address you want to assign to the eth0 interface. The "${ip_address}" should be replaced with the desired IP address, such as "192.168.0.100". This is where you specify the IP address that you want to assign to the eth0 interface.
So, when you execute the command "ifconfig eth0 ${ip_address}", you are telling the system to assign the specified IP address to the eth0 network interface card.
