How can I check my license details and expiry via the CLI?

I would like to check my license details and expiry via the CLI.

Which command should I use?

This is not possible in v5.8.1.x, v5.9.x.x or v6.1.1.x, but in v6.2.5.x and v6.2.6.x we have this functionality.

From the command line, use:

show license status
