HP-UX Fundamentals

Prerequisites:

An understanding of IT is required.

Course Description:

This course introduces the delegate to the main concepts of the HP-UX Operating System. The most commonly used commands are described in detail as are the command line wildcard and redirection facilities. The mechanisms by which a user acquires a login environment are discussed and the main features of the Korn/Posix/Bash Shells are introduced.

The course is designed to give delegates practical experience in developing and writing shellscripts. Most of the built-in shell commands are introduced together with the main program control structures.

The delegates will practise:

• Creating, copying, renaming, moving and deleting files and directories
• Using the shell's redirection and pipe facilities
• Editing text files using the vi editor
• Setting and changing access permissions on files
• Monitoring and controlling their own processes
• Using the basic file and text searching utilities
• Customising their own login environment
• 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
• Developing menu-driven shellscripts
