GNU Emacs has command line options to specify either a file to load and execute, or an Emacs Lisp function may be passed in from the command line. Emacs will start up, execute the passed-in file or function, print the results, then exit. [35] The shebang line #!/usr/bin/emacs --script allows the creation of standalone scripts in Emacs Lisp.

Emacs (/ ˈ iː m æ k s / ⓘ), originally named EMACS (an acronym for "Editor Macros"), [1] [2] [3] is a family of text editors that are characterized by their extensibility. [4] The manual for the most widely used variant, [5] GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". [6]
Ctrl+e : moves the cursor to the line end (equivalent to the key End). Ctrl+f : Moves the cursor forward one character (equivalent to the key →). Ctrl+g : Abort the reverse search and restore the original line. Ctrl+h : Deletes the previous character (same as backspace). Ctrl+i : Equivalent to the tab key.
While the line numbers are sequential in this example, in the very first "complete but simple [Fortran] program" published the line numbers are in the sequence 1, 5, 30, 10, 20, 2. [4] Line numbers could also be assigned to fixed-point variables (e.g., ASSIGN i TO n) for referencing in subsequent assigned GO TO statements (e.g., GO TO n,(n1,n2 ...
Editing locations therefore needed to be specified by context rather than by line number. The various looping and conditional constructs (which made TECO Turing-complete) were included in order to provide sufficient descriptive power for the correction tape. The terse syntax minimized the number of keystrokes needed to prepare the correction tape.
The Org Mode home page explains that "at its core, Org Mode is a simple outliner for note-taking and list management". [11] The Org system author Carsten Dominik explains that "Org Mode does outlining, note-taking, hyperlinks, spreadsheets, TODO lists, project planning, GTD, HTML and LaTeX authoring, all with plain text files in Emacs."
MicroEMACS is a small, portable Emacs-like text editor originally written by Dave Conroy in 1985, and further developed by Daniel M. Lawrence (1958–2010 [2] [3]) and was maintained by him. MicroEMACS has been ported to many operating systems , including CP/M , [ 4 ] MS-DOS , Microsoft Windows , VMS , Atari ST , AmigaOS , OS-9 , NeXTSTEP , and ...
In Emacs, the editing area can be split into separate areas called windows, each displaying a different buffer. A buffer is a region of text loaded into Emacs' memory (possibly from a file) which can be saved into a text document. Users can press the default C-x 2 key binding to open a new window. This runs the Emacs Lisp function split-window ...
