Tips

Intro

sys host includes the hostname.

sys host | get hostname

sys cpu returns one row per cpu.

sys cpu | length

Basic

Measure the hostname.

sys host | get hostname | str length

The cpu row count is a number.

sys cpu | length | math abs

Intermediate

Hostname length, then abs.

sys host | get hostname | str length | math abs

each can visit every cpu row.

sys cpu | each {|c| $c} | length

Advanced

Four steps from the hostname to a count.

sys host | get hostname | str length | into string | str length
