UNIX/LINUX/AIX/HP-UX/Solaris Introduction

Course Code



3-5 Days (depending on topics chosen)


This course provides participants knowledge of the basic features of UNIX (includes AIX, Solaris, HP-UX, Linux, and other products). This includes creating files and directories, assigning permissions, using the vi editor, and basic command line tasks such as sorting a file or searching for text within a file. This course is approximately 50% hands-on labwork.

This course is designed for individuals who are system and application end-users who have little or no experience with the UNIX operating system. Application support personnel, such as database administrators and 4GL programmers, who need a functional familiarity with basic system tools and commands will also find this class helpful.

Upon successful completion of this course, participants will be able to:

  • Use commands to manipulate files (including using the editor)
  • Navigate through the file system
  • Manage processes
  • Customize their environment
