|
|
Use this command to show logs for a specific device.
|
|
|
|
By default, the command prints all log messages and exit.
|
|
|
|
To continuously stream output, and see new logs in real time, use the `--tail` option.
|
|
|
|
Note that for now you need to provide the whole UUID for this command to work correctly.
|
|
|
|
This is due to some technical limitations that we plan to address soon.
|
|
|
|
Examples:
|
|
|
|
$ resin logs 23c73a1
|
|
$ resin logs 23c73a1
