This is a hands-on, instructor-led Korn Shell Training course delivered
on-site by instructor Leor Zolman. For those already familiar with
Unix fundamentals, this course teaches shell scripting: the primary
process-control mechanism for Unix and the glue that binds software
tools together. The course is taught using the Korn shell, the contemporary
de-facto standard shell for System V Unix.

the favor ;-) ]
