LinuxCBT KornShell Edition | 705MB | English
LinuxCBT feat. KornShell Edition focuses on the common Linux | Unix shell environment: Korn. It extends LinuxCBT Scripting Edition to 77 hours of content.

Kornshell derives largely from Bourne and C shells, incorporating many features from both. Kornshell also largely influenced the default Linux shell: BASH. Being familiar with Kornshell and BASH allows you to transport your skills across Linux and Unix systems with relative ease.
