help: '''
|
|
Use this command to show logs for a specific device.
|
|
|
|
By default, the command prints all log messages and exit.
|
|
|
|
To limit the output to the n last lines, use the `--num` option along with a number.
|
|
This is similar to doing `resin logs <uuid> | tail -n X`.
|
|
|
|
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,
|
|
and the tool won't notice if you're using an invalid UUID.
|
|
|
|
This is due to some technical limitations that we plan to address soon.
|
|
|
|
Examples:
|
|
$ resin logs 23c73a12e3527df55c60b9ce647640c1b7da1b32d71e6a39849ac0f00db828

$ resin logs 23c73a12e3527df55c60b9ce647640c1b7da1b32d71e6a39849ac0f00db828 --num 20
