KornShell (ksh) is a Unix shell which was developed by David Korn at Bell Labs in the early 1980s.
This repository is used to develop bug fixes to the last stable release (93u+ 2012-08-01) of ksh93.
This is free and open source software.
Key Features
- Job control, command aliasing, and command history designed after the corresponding C shell features.
- Choice of three command line editing styles based on vi, Emacs, and Gosling Emacs
associative arrays and built-in floating-point arithmetic operations (only available in the ksh93 version of KornShell). - Dynamic search for functions.
- Mathematical functions.
- Process substitution and process redirection.
- C-language-like expressions.
- Enhanced expression-oriented for and while loops.
- Dynamic extensibility of (dynamically loaded) built-in commands.
- Reference variables.
- Hierarchically nested variables.
- Variables can have member functions associated with them.
- Object-oriented-programming.
- Variables can be objects with member (sub-)variables and member methods.
- Object methods are called with the object variable name followed (after a dot character) by the method name.
- Special object methods are called on: object initialization or assignment, object abandonment (unset).
- Composition and aggregation is available, as well as a form of inheritance.
