Finding SAP system type (ABAP, Java or Dual stack) remotely (by software not person)

How I can tell an SAP system is ABAP or Java or Dual Stack through only command line remote access and by looking at processes running at OS level?

For example, I can see the following (when I install Linux trail version)

dw.sapNPL_DVEBMGS42 pf=/usr/sap/NPL/SYS/profile/NPL_DVEBMGS42_nplhost

/sapdb/NPL/db/pgm/vserver -sdbstarter 501 501 A -S 7200 -Y

/usr/sap/hostctrl/exe/sapstartsrv pf=/usr/sap/hostctrl/exe/host_profile -D sapstart pf=/usr/sap/NPL/SYS/profile/START_SCS00_nplhost icman -attach pf=/usr/sap/NPL/SYS/profile/NPL_DVEBMGS42_nplhost /usr/sap/NPL/DVEBMGS42/exe/igsmux_mt -mode=profile -restartcount=0 -wdpid=28707 pf=/usr/sap/NPL/SYS/profile/NPL_DVEBMGS42_nplhost /usr/sap/hostctrl/exe/saposcol -l -w60 pf=/usr/sap/hostctrl/exe/host_profile

The above are some of the examples of command line items I noticed on linux trail version.

I noticed that the default.pfl has system/type not mandatory in all servers so I cannot depend.

Assume that there is no physical person going through all this but a software needs to identify what type SAP system. Any recommendations are also appreciated

Thanks
