dev-server silently ignores unknown paramaters / qualifiers:
C:\GitHub\iobroker-community-adapters\ioBroker.shelly>dev-server watch --nodtart
Using profile default
Using profile name "default"
Using adapter name "shelly"
Install local iobroker.shelly
C:\GitHub\iobroker-community-adapters\ioBroker.shelly> npm pack
Packed to iobroker.shelly-10.2.0.tgz
C:\GitHub\iobroker-community-adapters\ioBroker.shelly\.dev-server\default> npm install "C:\GitHub\iobroker-community-adapters\ioBroker.shelly\iobroker.shelly-10.2.0.tgz"
^C
Commandline parsing should issue an error and abort if some parameter / qualifier is unknown to avoid processing while some options have been ignoere i.e. due to typo
