Device discovery and selection

You can list available devices, and select one to use for all subsequent commands:

  1. To list the devices:

    mbl-cli select

    For example:

    $ mbl-cli select
    Discovering devices...
    Select a device:
    1: mbed-linux-os-3006 (fe80::94f8:52ff:fe67:d5d8%enp0s20u1)
    2: No device
    mbed-linux-os-3006 (fe80::94f8:52ff:fe67:d5d8%enp0s20u1) selected
  2. To select a device, enter its number from the list above.

    For example, to select the device mbed-linux-os-3006, type 1.

    You can now omit the address argument from subsequent commands.

    The selected device's address is stored in a configuration file (${HOME}/.mbl.cfg), so the selection will apply to all subsequent runs of mbl-cli by the same user.

  3. To deselect a device: run select again and select a different device.

Remote command execution

To execute commands on the device:

  1. Select a device from the list of available devices using the mbl-cli select command.

  2. Run a command on the device:

    $ mbl-cli run <command> [address]

    The commands are run by the user root.

For example, to show the statuses of the active interfaces on a device:

$ mbl-cli run "ifconfig -a"

Get shell access (SSH)

To get shell access over SSH to a device (as the user root), use the shell command:

$ mbl-cli shell [address]

For a previously selected device, omit the address:

$ mbl-cli shell
Connecting to mbed-linux-os-3006...

After obtaining shell access, you can set up Wi-Fi on the device (see Setting up a network connection).
