Update nrf9160 modem firmware from Linux command line

Question

I want to be able to update both application firmware and modem firmware via the terminal. I know the nrfjprog and have no problem downloading application firmware. 
 Is it true that Nordic have no simple cli tool to update the modem firmware? 
 I know about nrfConnect and also the python package pynrfjprog ... and FOTA. But nrfConnect cannot be automatized by simple bash scripting. And pynrfjprog is not a complete solution (like nrfjprog )... it is a python package where you have to program a lot yourself. I know it might be a 30-35 lines for simple handling, but why do everyone need to do this, when it could be a standard feature of nrfjprog? 
 For pynrfjprog I have looked here: devzone.nordicsemi.com/.../214914 
 And FOTA is not practical in a production endvironment. 
 So is it at all possible with nrfjprog or a similar commandline tool to program modem firmware in a single command? 
 For example something like this: 
 nrfjprog --program <hexfile> -f NRF91 
 For reference I have been searching quite a lot around the community... but haven't been able to find answer. Only something like these which really aren't what I need:

Hi Carsten! 
 cvt1982 said: You say that prnrfjprog is just a wrapper for nrfjprog. So can you show me how to program the modem firmware directly from nrfjprog? 
 Yes, the pynrfjprog is a wrapper for nrfjprog, but also introduces more features than nrfjprog. E.g. the ability to program modem fw, which nrfjprog alone does not have. And this is something that is missing from nrfjprog IMHO. This is also reported to our nrfjprog team. 
 cvt1982 said: I have followed your guide on nRF Connect SDK (more specifically the Installing the nRF Connect SDK manually because I like to be in full control on my Linux setup) and I cannot find anything mentioned on the pynrfjprog. In the guide nrfjprog is highlighted as the tool to use (which "west" has to use during "west flash" commands). 
 As you mention in your initial post, the pynrfjprog may introduce more programming for a simple project where you simply want to compile and test your code. In a production environment it will allow the developer to program several devices with a production ready modem and application firmware. Both west and cmake/ninja uses nrfjprog to program the device, but only one device at the time. Once compiled the user can swap " west flash " or " ninja flash " with a python command that uses pynrfjprog to program both modem and application. 
 cvt1982 said: Maybe it is just me who are blind, but for some reason the pynrfjprog is a hidden project when looking at your default documentation (on nRF Connect SDK, user guides etc.). The first time I saw it was on a post here in the forums. 
 Yeah, I agree that it's not mentioned that much in use with nRF9160, but it is available under nRF Tools and via github . There should be more mentioning of this tool especially with regards to information on usage in production for nRF9160. Let me know if anything is unclear, or you need any more information and I will dig up some more for you 
 Kind regards, Øyvind
