Which command is used to display the current software version of RouterOS?

The command used to display the current software version of RouterOS is found within the system resource section of the command line interface. When you use the command to print system resources, it provides detailed information about the router, including the RouterOS version number. This command aggregates important data such as CPU load, memory usage, and specifically mentions the software version being used.

Using the command designated for printing interface information would not yield the RouterOS version, as it focuses solely on the various interfaces' details and their statuses. Similarly, while there are commands that might seem relevant, they would not effectively deliver the software version information in the comprehensive manner that system resource commands do. Thus, this command is specifically tailored to provide a quick overview of the essential system metrics, including the RouterOS version.
