Programmers, administrators and support personnel who need to understand existing shell scripts, automate procedures and write their own utilities.
Knowledge of the HP-UX Operating System to the level covered in the HP-UX Introduction course.
Some programming experience may also prove advantageous
The HP-UX Shell Programming course, together with the HP-UX Introduction and HP-UX System Administration courses, covers some of the topics required for the HP-UX 11i v3 System Administration (HP0-P20) exam.
The exam code HP0-P20 is based on HP-UX 11.31 release. This level of certification requires an individual to perform hands-on installation, configuration, administration and support of the HP Operating System in networked environments.
Following attendance on the relevant courses, delegates will need to dedicate time for self study and researching the topics covered on the course. They will also need to gain hands-on experience so they can put into practice what they have learnt on the courses.
Attending courses alone will not guarantee exam success, previous experience, practice, self study and aptitude are also key requirements. Before taking any exam, delegates should ensure they have the recommended experience by checking the HP website for current exam requirements and pre-assessment questionnaires.
Exams are not included as part of the course nor in the course fee.
