I am not able to run commands with nrfjprog using the J-link Segger device
e.g. nrfjprog --family nrf52
I can do it only with the Keil or Segger UI environment
How can I run scripts using the J-link device?

Hello,
Are you getting any errors when you run "nrfjprog --family nrf52". Also, what OS do you use, windows, linux, or macos?
You can find the documentation for nrfprog here: nRF5x Command Line Tools
