I discovered that Ubuntu 20.04 (Focal Fossa) Server edition doesn’t have ifconfig command pre-installed. How then can you install ifconfig on Ubuntu 20.04 (Focal Fossa)?. if you get a message ifconfig: not found on Ubuntu, it means the command is not installed. ifconfig is a command line interface tool for network interface configuration.
The ifconfig command is deprecated and the ip command is now favored to provide similar functionality. See our guide on ip command usage:
