Useful tips and points to note when using nano.
Correct Usage of Command Name and Options
Forms like 'nano-w-w-w-w-w' are a miscombination of the 'nano' command and the '-w' option. The correct usage is to separate the command and options with a space, like 'nano -w [filename]'. Specifying an option once is sufficient, and repeating it multiple times has no additional effect.
