|
|
Use this command to update the Resin CLI
|
|
|
|
This command outputs information about the update process.
|
|
Use `--quiet` to remove that output.
|
|
|
|
The Resin CLI checks for updates once per day.
|
|
|
|
Major updates require a manual update with this update command,
|
|
while minor updates are applied automatically.
|
|
|
|
Examples:
|
|
|
|
$ resin update
|
|
'''
|
|
action: (params, options, done) ->
|
|
npm.isUpdated packageJSON.name, packageJSON.version, (error, isUpdated) ->
|
|
return done(error) if error?
|
|
|
|
if isUpdated
|
|
