nRF Util comes with different levels of help options:
| Command | Description |
|---|---|
-h |
Add to a command to display concise help for the command in the command line. For example, nrfutil device -h for the device command. |
--help |
Add to a command to display extended help for the command in the command line. Compared with the -h command, this will display the help with some additional details. |
--help-extended |
Add to a command to open the comprehensive help guide in your browser for the command. These quick guides are also available in this documentation. |
The help text in --help and -h groups parameters as options and arguments:

Help is context-sensitive. If you need usage instructions while writing a command, you can use -h and --help, regardless of any other arguments supplied.
For example, the following command shows the usage instructions for nrfutil device program:
nrfutil device program --firmware firmware.hex --help
