## Details

Print the device ID for this CLI installation as "`<os>:<uuid>`".

The UUID is generated on first use and stored in the config file.
The OS prefix (e.g. darwin, linux) is added at print time so you
can identify the machine and platform at a glance. The same UUID
is sent with every OAuth authorization request, so you can match
a token in the CircleCI UI back to this installation.

JSON fields: device_id (string) — stable identifier in the form `<os>:<uuid>`
