The Pico (Pine composer) is a text editor for the Unix and Unix-based computer systems. This has been designed by the Office of the Computing and Communications at the University of Washington and combined with the Pine e-mail client. This document also describes Pico, Pine’s default text editor, which you automatically use when you compose a message. It prompts and other on-screen information will be presented in typewriter style type.
The Pine’s message composition editor is also available as a separate stand-alone program, called PICO. The PICO is a very simple and easy-to-use text editor that offers the paragraph justification, cut/paste, and a spelling checker.
Syntax: pico filename.extension
