Thanks for the quick reply, really appreciated.
Could you please clear one of my understanding that, now I have left with 2 options if I don't buy vcentre software and want to do automation on debian server,
1. I can make a use of soap APIs, (Probably using pyvmomi python library)
2. I can use vSphere CLI for vSphere 6.7 (Which is in perl, so need to know perl first in order to make use of it)
Thanks again,
Latif
