If we run sys we receive a table which contains tables itself:

> sys

To access one of the embedded tables we can use the get command

> sys | get cpu

───────┼───────────────────┼────────────────────┼───────────────────

There's also the ability to pass multiple parameters to get which results in an output like this

sys | get cpu battery
