This Solaris Korn Shell Programming training course is designed to give delegates practical experience in developing and writing shell scripts.
Course overview:
Most of the built-in shell commands are introduced together with the main program control structures. The course also gives practical experience using a range of Solaris tools to manipulate text and incorporate into Solaris shell scripts.
