What text editor can I use on UBOS?
/docs/gears/faq-howto-troubleshooting/faq-text-editors/
By default, we install vi.
Alternatively you can use vim or nano. (If you are not already

First you need to install the package, e.g.
% sudo pacman -S nano
and then you can use it to edit a file, e.g.
% nano myfile
