HP-UX Posix Shell Programming Course Overview This Hewlett Packard HP-UX Posix Shell Programming training course is designed to give delegates practical experience in developing and writing shell scripts. 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 HP-UX tools to manipulate text and incorporate into HP-UX shell scripts.
COURSE OBJECTIVE:
Course Objectives To provide the skills needed to develop and customise shell programs and to make effective use of a wide range of standard HP-UX programming and development tools.
TARGET AUDIENCE:
Who will the Course Benefit? Programmers,developers and system administrators who need to construct shell scripts and process text files using advanced text handling facilities. The HP-UX Posix Shell Programming course assumes knowledge of the HP-UX Operating System to the level covered in the HP-UX Introduction course. Some programming experience may also prove advantageous.
