The Korn shell is a Unix shell that was developed by David Korn at AT&T Bell Labs in the late 1970s. It was intended to be a successor to the Bourne shell, which was the default shell on Unix systems at the time.
The Korn shell adds many features that are missing from the Bourne shell, such as:
- Command line editing
- User-defined functions
- Aliases
- Arrays
- Integer arithmetic
- Job control
It also includes some features that are unique to itself, such as:
- A history mechanism
- A built-in programming language
The Korn shell is the default shell on many Unix systems, such as AIX, HP-UX, and Solaris. It is also available as a standalone program for other operating systems, such as Windows.
What is C shell and Korn shell?
C shell (csh) and Korn shell (ksh) are two different shells.
C shell is a Unix shell created by Bill Joy while he was a graduate student at the University of California, Berkeley in the late 1970s. It was originally released as a shell for Version 7 Unix.
The Korn shell is a Unix shell created by David Korn at AT&T Bell Labs in the early 1980s. It was released as a commercial product in 1993.
Both shells have different syntax and features.
What is Korn shell known as?
The Korn shell is a command interpreter that was developed by David Korn at AT&T Bell Labs in the early 1980s. The Korn shell is known for its features that include:
- Command history
- Aliases
- Job control
- Arithmetic expressions
- Extended I/O redirection
- Functions
The Korn shell is also known for being compatible with the Bourne shell, which is another popular command interpreter.
Who uses Korn shell?
The Korn shell (ksh) is a Unix shell that was created by David Korn at Bell Labs in the early 1980s. It was intended to be a replacement for the Bourne shell (sh), which was the standard shell at the time.
The Korn shell added many features that were missing from the Bourne shell, such as user-defined functions, integer arithmetic, and an increased range of flow control constructs. It also included many features from the C shell (csh), such as aliases and command history.
The Korn shell was eventually included as a standard shell in many Unix systems, including AIX, HP-UX, IRIX, and Solaris. In addition, many commercial Unix products, such as IBM's Tivoli Storage Manager, include the Korn shell.
The Korn shell is also used by many people who don't use Unix or any of the aforementioned products. For example, the Korn shell is available for Windows and is popular among developers who need to port Unix shell scripts to Windows. Is ksh better than Bash? There is no definitive answer to this question as it depends on individual preferences and needs. However, many people find ksh to be a more powerful and feature-rich shell than Bash, particularly when it comes to handling complex command line operations. Is the Korn shell free? Yes, the Korn shell is free. It is released under the GNU General Public License, which allows anyone to use, modify, and redistribute the software.
