The nano text editor is increasing in importance and it is the default editor in many systems. Personally, I don't like the navigation or the lack of navigation features that it has. It can be customized in the same way as vim. This time, we will edit the $HOME/.nanorc file. Your edited file should look something like the following:
set autoindent set tabsize 4 include /usr/share/nano/sh.nanorc
The last line enables syntax highlighting for shell scripts.
