HP UX Basics

1. Unix Operating System:

   • HP-UX is a Unix-like operating system, which means it follows the Unix principles and architecture. It provides a multi-user, multitasking environment with a command-line interface.

2. Kernel:

   • The kernel is the core component of the operating system that manages system resources and provides essential services. In HP-UX, the kernel is responsible for memory management, process scheduling, device drivers, and other low-level functions.

3. File System:

   • HP-UX supports various file systems, including HFS (Hierarchical File System) and VxFS (Veritas File System). The file system organizes and stores data on disk drives.

4. Shell:

   • HP-UX uses shells (command interpreters) for interacting with the operating system. The default shell is usually the Bourne shell (sh), but other shells like Korn shell (ksh) and the C shell (csh) are also available.

5. User Accounts:

   • Like any Unix system, HP-UX supports multiple user accounts. Each user has their own home directory, and user permissions are managed through file permissions and access control lists.

6. Command-Line Interface (CLI):

   • Interaction with HP-UX is primarily through the command-line interface. Users execute commands to perform tasks, and scripts can be created for automation.

7. Processes:

   • HP-UX is a multitasking operating system, allowing multiple processes to run concurrently. Users can initiate processes and manage them using commands.

8. Networking:

   • HP-UX includes networking capabilities for communication between systems. It supports TCP/IP networking protocols, allowing HP-UX systems to connect to networks and the internet.

9. System Administration:

   • System administrators perform tasks such as user management, system configuration, software installation, and maintenance. System administration is typically carried out using command-line tools and configuration files.

10. Security:

    • HP-UX provides security features, including user authentication, file permissions, and access controls. System administrators can configure security policies to protect the system and its resources.

11. Performance Monitoring:

    • Tools are available for monitoring system performance, including commands to check CPU usage, memory utilization, and disk I/O. Performance monitoring helps administrators optimize system resources.

12. System Logs:

    • HP-UX maintains system logs that record events, errors, and activities. System administrators can review logs to troubleshoot issues and monitor system health.

13. Software Installation and Management:

    • HP-UX uses a package management system to install, update, and remove software packages. The software depot is a repository of software packages that can be installed on the system.

14. Hardware Support:

    • HP-UX is designed to run on HP's proprietary hardware platforms, providing optimized support for HP servers, workstations, and related devices.

Before learning HP-UX basics, it's beneficial to have a foundational set of skills that will help you navigate and understand the Unix-like operating system environment. Here are some recommended skills:
