There is not a command line per se, but there is what is called the Message-based Software Development Kit (MBSDK), which is how our Process Manager product interacts without LANDesk without the console. There is also a regular SDK.
All Core Server 8.8 and later will have the MBSDK installed. I know that if you get a copy of the full SDK, you get some help documentation on the MBSDK, but I don't know much more.
There is also a LANDesk SDK (different than the MBSDK) which I use for my LANDesk Support Tools.
first of all thank you for your quickly answer, It is very important for me!
