How can you view the system's IP address in Linux?

To view the system's IP address in Linux, the command ip addr is the most accurate and widely used method. This command is part of the iproute2 package, which provides advanced networking commands for managing system networking. When executed, ip addr displays detailed information about all network interfaces on the system, including their IP addresses, network masks, and other related settings.

Using ip addr is preferred over older commands like ifconfig, as it offers more powerful and flexible querying capabilities. It provides not just the IP address, but also the interface status and additional configuration details. This makes it an essential tool for network administrators and users needing to diagnose networking issues or configure their systems.

The other choices do not correctly represent commands used in Linux for this purpose. For instance, get ip and show ip do not exist in standard Linux command-line tools, while ip show is not a recognized command under the ip utility. Hence, ip addr is the correct choice for viewing the system's IP address in Linux.
