I apologize if this is a FAQ, but I have been searching and just not finding what I am looking for. I am looking for a command-line program that can read and update parameters from STDIN. In particular, I would really like to be able to run something like rtl_fm and be able to change the tuned frequency from the command line *without* needing to re-start the application. Does this make sense?

I have an rtl-sdr v3 that I can use, but would love it if there were an option that would run my Airspy HF+. I am using a raspberry pi and would like to stick to the command line.
