This Hewlett Packard HP-UX Posix Shell Programming training course is designed to give delegates practical experience in developing and writing HP-UX shell scripts. Most of the built-in shell commands are introduced together with the main program control structures. This course is not suitable for C shell programmers.
The delegate will learn and acquire skills as follows:
- Writing simple scripts to enhance basic command output
- Using the various shell quoting mechanisms appropriately
- Manipulating shell variables and user-defined variables in scripts
- Implementing conditional execution facilities
- Using the shell's built-in loop constructs where appropriate
- Writing scripts to trap user interrupts
- User defined Functions
- Developing menu-driven shell scripts
Programmers, administrators and support personnel who need to understand existing shell scripts, automate procedures and write their own utilities.
The 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.
To provide the skills needed to develop and customise shell programs.
This HP-UX Shell Programming course, together with the HP-UX Introduction and HP-UX Administration courses, covers some of the topics required for the HP-UX 11i v3 System Administration (HP0-P20) exam.
Before taking any exam, ensure you have the recommended experience. The HP-UX website lists all exam requirements and these are updated regularly.
Exams are not included as part of the course.
