What is the difference between KSH and BASH?

KSH and BASH are shells in the field of computer programming; they both have their different features and command. KSH and BASH have programmable shells and command processors in Linux and UNIX computer systems.

KSH stands for “Korn shell.” It was developed by David Korn. Korn shells allow the developer to create new shell command when needed, it is older than BASH, and it has fewer resources, which only attracts limited scope of users. Korn shells have released different versions like PDKSH, MKSH, and KSH88, which is the latest version.

BASH stands for “Bourne Again Shell.” It was created by the freeware software foundation, and it is widely used in the open source communities since it is free of charge. BASH was created years after KSH, which makes it have numerous resources that attract the multitude.

One of the things that you should know is that KSH stands for The Korn Shell. This has been developed way before BASH was developed. Even though KSH was developed first, BASH is now more popular.

This already comes with a more added extension, which means that it can do some of the things that KSH can do, such process substitution, history completion, and even command-line editing. What KSH can do better is to make sure that it will do its command print better.

The echo command of the KSH is also better as compared to BASH. If you would like to use something that will be able to handle exit codes better, BASH is still the better option that is available for you.
