Creating uci-default by uci export

I'm new to OpenWrt, sorry.
I found Firmware Selector and the ability to add my own startup script (uci-defaults). I have a router configured and I would like to get the configuration from it as a uci script. The Internet told me about the uci export command, but this command does not produce the uci set ... something line.

I have something like this, it looks like a configuration file from /etc/config:

config wifi-iface 'default_radio0'
	option device 'radio0'
	option network 'lan'
	option mode 'ap'
	option ssid 'OpenWrt'
	option encryption 'psk2'
	option key 'OpenWrt1'

syntax is as posted in Correct uci-defaults, how to setting samba and adguarhome? or Linksys MR8300.

Why did you not ask uci?

So you might like to try uci show wireless.....
