Unix

You will learn how to

• Manage data, execute commands and customise your UNIX environment
• Locate files by name, owner, type and other characteristics
• Navigate the UNIX directory hierarchy, manipulate files and control file access
• Interact with and customise the KornShell
• Extract and process information with filters and pipes
• Develop shell scripts to simplify and automate frequent tasks

Course benefits
UNIX is a highly reliable multiuser, multitasking operating system for platforms ranging from mission-critical clusters and servers to workstations and desktops. To effectively support UNIX systems and the applications they run, a strong background in the structure of UNIX and its many utilities is essential.

In this course, you gain the fundamental knowledge and skills necessary to take full advantage of this powerful and flexible system.

Who should attend
This course is valuable for user and application support specialists, software developers, or anyone working towards becoming an effective system, network or database administrator on a UNIX platform.

• Managing files and directories
• Changing file access permissions
• Customising the KornShell environment
• Accessing a UNIX server
• Locating files with find
• Searching, sorting and restructuring data with filter commands
• Creating and executing shell scripts
• Building a take-home "tarball" archive
