Pico text editor
Pico is a simple, display-oriented text editor based on Pine. Pico is very simple to use and offers features such as paragraph justification, cut/paste, spelling checker, search and replace, etc. However, this program doesn’t have as many features as some other popular Linux text editors (such as vi).
Pico is not truly open source, and most Linux distributions don’t even include Pico as a text editor. In fact, Ubuntu even links the command pico to nano.
