Command Line Interfaces and Text-based Shells
The original Amiga CLI (Command Line Interface) had some basic editing capabilities, command templates, and other features such as ANSI compatibility and color selection. In AmigaOS 1.3, the program evolved into a complete text-based shell called AmigaShell.
Third-party developers created improved shells because implementing a new command line interface into Amiga only required replacing the original Console-Handler standard command line device driver (or "handler" in Amiga technical language). This program controlled text-based interfaces into Amiga. The most famous Amiga replacement for the original Console-Handler was KingCON (also known as its "virtual device" name added with semicolon "KingCON:").
Some well-known shells from other platforms were ported to Amiga. These included Bash(Bourne Again SHell), CSH (C-Shell), and ZSH (Z-Shell). The shells taken from Unix and Linux were adapted into Amiga and improved with its peculiar capabilities and functions.
The MorphOS Shell is an example of Z-Shell mixed with the KingCON console handler. It originated as a Unix-like shell, and is provided with all the features expected from such a component: AmigaDOS commands (more than 100 commands, most of which are Unix-like), local and global variables, command substitution, command redirection, named and unnamed pipes, history, programmable menus, multiple shells in a window, ANSI compatibility, color selection, and so on. It also includes all the necessary commands for scripting.

Famous quotes containing the words command, line and/or shells:
“I, who should command a regiment,
Do amble amiably here, O God,
One of the neat ones in your awkward squad.”
—Norman Cameron (b. 1905)
“We are apt to say that a foreign policy is successful only when the country, or at any rate the governing class, is united behind it. In reality, every line of policy is repudiated by a section, often by an influential section, of the country concerned. A foreign minister who waited until everyone agreed with him would have no foreign policy at all.”
—A.J.P. (Alan John Percivale)
“It is not easy to make our lives respectable by any course of activity. We must repeatedly withdraw into our shells of thought, like the tortoise, somewhat helplessly; yet there is more than philosophy in that.”
—Henry David Thoreau (1817–1862)
