JOE or Joe's Own Editor (JOE is a recursive acronym) is a terminal-based text editor for Unix systems, available under the GPL. It is designed to be easy to use.[2][3]
joe is distributed in most major Linux distributions[4][5][6][7][8][9] and open-source BSD systems.[10][11][12]

Description of features
JOE includes an integrated help system and a reminder of how to get help is always on the screen. The key sequences in JOE are similar to those of WordStar and Turbo C: many are combinations of the Control key and another key, or combinations of Ctrl+K and another key, or combinations of the Escape key and another key. Numerous settings are also available through Ctrl+T. The program is generally customizable through an extensive configuration file, and it supports color syntax highlighting for numerous popular file formats, a feature that is also configurable.
JOE comes with macro files that help it emulate Emacs (when invoked as jmacs; though it lacks the lisp programmability of Emacs), Pico (when invoked as jpico), or WordStar (when invoked as jstar). There is also a variant called "rjoe", which is restricted in that it allows one to edit only the files specified on the command line (which can be useful to enforce the principle of least privilege).
The editor reminds of the DOS editors, but it includes the typical Unix editor features such as internal command history, tab completion in file selection menus, regular expression search system and the ability to filter (pipe) arbitrary blocks of text through any external command.
History
JOE was among the default editors in the early popular Linux distributions,[13][14][15][16] which gave it some prominence and helped build a user base[17][18], so it continues to be included as an option in Linux and BSD distributions, sometimes in the critical role as a "rescue mode" editor[7].
After version 2.8 was released by Joseph Allen in 1995, the development cycle had halted for several years. The development was taken over by a new group of enthusiasts in 2001, led by Marek Grac, who released 2.9 and several later versions, introducing a standardized build system and fixing many bugs. Allen returned to the project in 2004 and released version 3.0, which introduced syntax highlighting and support for UTF-8.[19]
