A KornShell developer designs, writes, tests, and debugs scripts in KornShell (ksh), a high-level programming language primarily used for text and file handling. They automate routine tasks, manage system processes, and perform data manipulation. They are also responsible for analyzing and resolving issues related to the KornShell scripts. They often work closely with system administrators and software engineers to integrate KornShell scripts into larger systems. Moreover, they are expected to understand Unix/Linux operating systems, as KornShell is a Unix shell. They may also be involved in enhancing the shell's features or fixing bugs to improve performance and functionality.
