I needed an easy way to make Wifi connection on my Raspberry Pi, without the need to remember lines of 40+ chars with parameters, that you don't even know or remember while typing. Also it had to be on the terminal and because nmtui didn't fit in the little screen of my cyberdeck, i had to invent another way.

The script uses nmcli and fzf and can run on any sized terminals. You can list available networks, select them and make a connection, enable/disable the wifi adapter and edit an existing connection. Just for convenience you can also run raspi-config.

Edit 2024/10/29:

Added some more features.

• Show saved connections
• Connect to saved and new connections
• Show Wifi status
