CLI Machines Power Power Status

`ed machines power status`

Says whether the machine has a live shared connection, what MAC address is stored for it, and which of wake and reboot are possible right now. It is the default subcommand of power, so ed machines power tuf runs it.

ed machines power status <machine> [--json]

Arguments

Name	Type / values	Default	What it does
`<machine>`	machine name, ssh alias or id	required	Which machine to report on. Resolved by name, alias, id or unambiguous prefix.

Options

Name	Type / values	Default	What it does
`--json`	flag	off	Emit JSON on stdout instead of the table. Long form only, there is no `-j`.
`--help`, `-h`	flag	off	Print the help for this command on stdout and exit 0.

One row, five columns:

$ ed machines power status tuf
MACHINE     CONNECTED  MAC                WAKE  REBOOT
Asus TUF 7  yes        04:42:1a:8d:2f:6c  yes   yes

MAC prints - when Edith has never learned one.

`--json` shape

{
  "canReboot": true,
  "canShutDown": true,
  "canWake": true,
  "connected": true,
  "macAddress": "04:42:1a:8d:2f:6c",
  "machine": "Asus TUF 7"
}

machine is the display name, not the id. macAddress is null rather than missing when none is stored, and canWake is exactly macAddress != null. canReboot and canShutDown are both copies of connected.

Examples

ed machines power status tuf
ed machines power tuf
ed machines tuf power
ed machines power status tuf --json | jq -r '.canWake'

Behaviour notes

This is the one command on the page that never touches the network. connected is a local test: it looks for the ControlMaster socket file for that machine and runs ssh -S <socket> -O check against it. A machine that is up and reachable but has no open shared connection reports connected: false, which is no in the table.

Read that as a promise about cost, not about capability. canReboot: false means there is no open channel to reuse, not that a reboot would be refused: ed machines power reboot opens its own connection when there is none. What it does tell you is that the next command will pay for a fresh SSH handshake.

Nothing is mutated. The only failure is an unknown machine, which exits 3.
