Editing Graphical user interface (section)

=== GUI wrappers ===
GUI wrappers find a way around the [[command-line interface]] versions (CLI) of (typically) [[Linux]] and [[Unix-like]] software applications and their [[text-based user interface|text-based UI]]s or typed command labels. While command-line or text-based applications allow users to run a program non-interactively, GUI wrappers atop them avoid the steep [[learning curve]] of the command-line, which requires commands to be typed on the [[Computer keyboard|keyboard]]. By starting a GUI wrapper, [[user (computing)|users]] can intuitively [[human–computer interaction|interact]] with, start, stop, and change its working parameters, through graphical [[icon (computing)|icons]] and visual indicators of a [[desktop environment]], for example. Applications may also provide both interfaces, and when they do the GUI is usually a WIMP wrapper around the command-line version. This is especially common with applications designed for [[Unix-like]] operating systems. The latter used to be implemented first because it allowed the developers to focus exclusively on their product's functionality without bothering about interface details such as designing icons and placing buttons. Designing programs this way also allows users to run the program in a [[shell script]].
