Korn Shell was developed in Bell Labs by David Korn and the year was 1980. But it was announced later at USENIX on 14th July 1983. The Korn shell has most of the features which one can be found in the bourne shell as well as the c shell. The extension of the Korn shell is .ksh. It provides better performance in terms of the execution of any scripts or commands. We can locate the Korn shell in /bin/kash.                

Bash Shell is a Unix shell that was developed by Brian Fox. The Bash shell stands for ‘Bourne-Again shell’. This was first released in the year 1989. For most Linux distributions, it is used as the default login shell. We can use the bash shell for reading or executing any command. The basic feature of the bash shell is all taken from sh. There are also different features like history which are copied from csh and ksh. 


Following is a table of differences between Korn Shell and Bash Shell:
