nano is a character terminal text editor, a bit like the editor program under DOS. It is much simpler than vi / vim, more suitable for Linux beginners. Some Linux distributions default editor is nano.
nano command to open the specified file for editing, by default it will automatically break the line, automatically split into several lines ie input is too long in a row, but in this way to deal with some files may cause problems, For example, the Linux system configuration files, automatic line break will only write the original content on one line broken into multiple lines, and may cause the system not working. So, if you want to avoid this situation, coupled with the -w option on it.
