Action "service.status"

Status of a service. Note, does not throw an error if service is not installed.

Output

$status
Indicates if the startup behavior has changed.

Example

const {$status} = await nikita.service.status([{
  name: 'gmetad'
})
console.info(`Service status: ${$status}`)

Notes

Historically, we had the following two config:

code_started (int|string|array)
Expected code(s) returned by the command for STARTED status, int or array of int, default to 0.
code_stopped (int|string|array)
Expected code(s) returned by the command for STOPPED status, int or array of int, default to 3.

We might think about re-integrating them.
