KornShell

KornShell(Corn shell,ksh ) Was a kind of, developed early () and announced at the annual conference on July 14, 1983. Early Bell Laboratories developer Mike Wiech and Pat Sullivan were also involved in development and wrote the style and style code of the input line edit mode respectively. It is fully upwardly compatible with, and incorporates many functions such as command history. He is said to have developed ksh in response to user requests within Bell Laboratories.

design

KornShell, Shell and Utilities, Command Interpreter (IEEE Std 1003.2-1992) Compliant.

The main differences between the conventional Bourne shell and KornShell are as follows.

Functions derived from * (), (), () have been added. When used in interactive mode, ksh can edit command line by way of wind. Move the cursor up You can call up the previously entered command line by key operation and edit that command line to use the line mode editor. The key operation at this time can select compatibility mode and compatible mode. `ksh 93 ', and computing functions are built in.

history

Until 2000, KornShell was holding the rights of AT & T. Then it became under AT & T proprietary license, from 93q in 2005 It was distributed at. KornShell is AT & T Software Technology (AST) Open Source Software It is available as part of the Collection. ks Was originally available only with AT & T's commercial license, so a number of open source alternative implementations were born. It includes public domain pdksh,mksh, ,, and so on.

The function of ksh88, the first KornShell, is Shell and Utilities, Command Interpreter (IEEE Std It is the source of 1003.2 - 1992).

Some vendors still use the old ksh88 as/ bin / ksh, and sometimes extend themselves. ksh 93 'is still maintained by the author Corn.ksh93is followed by an alphabet character to indicate the version, the latest version is ksh93u. That one wasksh93t +, before that wasksh93t`. An intermediate version for bug fixes may be released without changing this version string.

Dtksh, which is a desktop KornShell, isksh93 distributed as part of. This version provides mapping at the shell level of widgets, intended to counter with.

The first KornShell ksh88 is assumed to be the default shell of AIX from version 4, and ksh93 is prepared separately.

Derive

Derived software from KornShell is shown below.

• dtksh - a fork fromksh93. Part of.
• tksh - a fork fromksh93. Provide access to.
• oksh - fork of version KornShell. Only works with. () Is used as the default shell.
• mksh - Implementation of KornShell. Developed with ().
• SKsh - version KornShell. () And other interactions with Amiga.
• MKS Korn shell - Commercial implementation by MKS. (SFU) version 2.0 up until now. According to David Corn, MKS Korn Shell as of 1998 was not fully compatible with KornShell. SFU version 3.0 introduced a new POSIX.2 compliant shell as a substitute for MKS Korn shell.
• Developed by David Kohn () is a UNIX compatible package on Windows and includes KornShell.
