Introduction to nano

nano is a text editor in Unix and Unix-like systems (including Linux) and is a copy of Pico.

Pico is a text editing program written and maintained by the Computing and Communications Group at the University of Washington.

nano is a character terminal text editor, a bit like the editor program under DOS. It is much simpler than vi/vim and is more suitable for Linux beginners. The default editor for some Linux distributions is nano.

The nano command can open the specified file for editing. By default, it will automatically break lines, that is, automatically split into several lines when too long content is entered in one line. However, some files are processed in this way. It may cause problems. For example, in the configuration file of the Linux system, automatic line breaking will cause the content that can only be written on one line to be broken into multiple lines, which may cause the system to malfunction. Therefore, if you want to avoid this situation, add the -w option.
