| #### CATEGORY=Device discovery |
| ### set the default device to interact with |
| |
| ## usage: fx set-device [<device-name>] |
| ## |
| ## fx set-device is used to specify the default device to target for various |
| ## fx commands, such as serve, syslog, and so on. |
| ## A device is set within the scope of a build directory (i.e. out/arm64 may |
| ## have a different pair set than out/x64). |
| ## |
| ## If no device name is given, set-device will attempt to discover devices. If |
| ## one device is found, that device is set as the default for the current build |
| ## directory. If more than one device is found, the user must select one and |
| ## provide it to a subsequent invocation of the command. |
| ## |
| ## To unset, use `fx unset-device`. |
