How to use Windbg for opening a dump and launching some Windbg commands from the command prompt?

Question

As mentioned in this other question, I'd like to start Windbg, open a dump, and launch some commands (.load pykd.pyd and !py heap_stat.py).

I thought this would be easy, but even starting Windbg and open a crash dump seems not that easy, as you can see from following unsuccessful examples:

Prompt>windbg.exe /?
Prompt>windbg.exe --help
Prompt>windbg.exe E:\Bugs\program.exe_181212_215503.dmp
Prompt>windbg.exe -D E:\Bugs\program.exe_181212_215503.dmp
Prompt>windbg.exe -zertyuiopqsdfghjklwxcvbn
Prompt>windbg.exe -help
Prompt>windbg.exe help

The idea is to get something like:

Prompt>windbg.exe -d <dumpfile> -c <command1;command2>

Answer 1

it is documented and available in both windbg.chm as well as command prompt -? note i use it on cdb which is console mode not on windbg
windbg -? , -h , --help , /? , -B#llCr@p
everything should should pop up the debugger.chm (broken in 17763 but check say 14951)

C:\>cdb -? | grep -i dump
  -openPrivateDumpByHandle <HANDLE>
    specifies the handle of a crash dump file to debug
  -z <CrashDmpFile> specifies the name of a crash dump file to debug
  -zd <CrashDmpFile> specifies the name of a crash dump file to debugand
                     deletes that crash dump after the debugger has finished
                      crash dump
