There are multiple ways to install Emacs on Ubuntu 22.04 Jammy JellyFish Linux using the command terminal and graphical user interface.
GNU Emacs is a programmable text editor suitable for development. It is a very comprehensive and platform-independent editor that can be expanded with its own Lisp dialect (Emacs Lisp). GNU Emacs makes it easier to write source code through syntax highlighting and can be adapted by the user. Since its control is mainly based on keyboard shortcuts, it requires some training to be able to use all its possibilities intensively. Thanks to a large number of plugins, the editor can be used in almost all areas. There are, for example, extensions for file management, email and news, IRC, compilations, web surfing, and much more. Furthermore, it can also be used to create text documents based on LaTeX.
