Design
KornShell complies with POSIX.2, Shell and Utilities, Command Interpreter (IEEE Std 1003.2-1992.)
Major differences between KornShell and the traditional Bourne shell include:
- Job control, command aliasing, and command history designed after the corresponding C shell features;
- Three WYSIWYG-style line editing modes designed to make an interactive shell session behave like vi, Emacs, or XEmacs;
- Associative arrays and built-in floating point arithmetic operations (only available in the ksh93 version of KornShell.)

Famous quotes containing the word design:
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
