How to disable wrapping lines in nano?

To change persistent settings for nano, we can edit the user-specific .nanorc file (/home/user/.nanorc). This file contains configuration settings that nano loads on start-up.

To disable line-wrapping, we need to specify the nowrap directive. Add this line to .nanorc:

set nowrap 

We may need to create this file if it doesn't exist. For more information about the available settings in this file, see the .nanorc man page:

$ man nanorc
