nano

Character terminal text editor

Supplementary instructions

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 inputting too long content in one line. However, processing some files in this way 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.
