A quick tip for GNU Nano – the text editor. Ever receiving the terminal error when using nano?

[root@srv ~]# nano                                                        
Error opening terminal: unknown.
[root@srv ~]#

Under chroot or container (like docker) environment try exporting the TERM environment:

export TERM=linux

And then execute nano the chances are you will enter nano normally and do your work (faster than vim 🙂 )?

You may use it without exporting to your shell, but just the for the nano:

TERM=linux nano
