Course Description:

This course will cover basic command necessities such as the file system structure, core UNIX commands and how to use them together, simple text editing, the UNIX command environment and how to use it to your advantage. You will also learn how to use common UNIX utilities to send mail and transfer files between machines, and how to automate tedious tasks to save time and effort.

• Understand the history and evolution of UNIX operating systems

• Connect and log on to machines running UNIX

• Understand the structure and purpose of the UNIX file system; Use UNIX commands to move about the UNIX file system

• Understand and manipulate UNIX file permissions

• Create and edit files using the vi editor

• Understand the basic features of various UNIX shells

• Manipulate shell variables to configure your environment

• Use UNIX utilities to identify, manipulate, and search UNIX files

• Understand the UNIX user and group paradigms

• Understand KORN shell basic programming constructs

• Create KORN shell variables

• Manipulate strings using KORN shell commands

• Use advanced commands of vi

• Perform KORN shell arithmetic

• Use conditional logic within KORN shell scripts

• Execute a series of commands repetitively (loop)

• Put together sets of commands you use in the KORN shell into a script

• Debug your KORN shell scripts

Who Needs to Attend:
