dhclient: Get an IP address for the `eth0` interface.
$ sudo dhclient ${eth0}
try on your machine
The command "sudo dhclient ${eth0}" is used to request and obtain an IP address lease from a Dynamic Host Configuration Protocol (DHCP) server for the network interface "eth0".
Here's a breakdown of the command:
- "sudo": It is a command in Linux/Unix systems that allows users to run programs with the security privileges of another user, usually the root user. In this case, it runs the subsequent command with administrative privileges.
- "dhclient": It is a command-line DHCP client that is used to obtain the necessary network configuration information from a DHCP server, such as an IP address, subnet mask, default gateway, and DNS server addresses.
- "${eth0}": It is a variable that represents the network interface named "eth0". Network interfaces are usually named eth0, eth1, wlan0, etc., depending on the system configuration.
By running this command with sudo, it will send a DHCP discovery request to the DHCP server associated with the network interface "eth0" and obtain the necessary IP address configuration.

never run a command you are not sure if it is safe.
