Develop Intelligence
Introduction to Linux System Administration
Learn how to effectively administer your own Linux dev box.

The Introduction to Linux System Administration training course is a variation of the DevelopIntelligence Linux System Administration course, tuned and targeted at software developers, quality assurance engineers, and software configuration management engineers.

Instead of spending the entire time focusing on how to setup, configure, and administer a linux machine, the course focuses on the common configuration elements and core command-line tools to effectively work in the linux environment.

Introduction to Linux System Administration course can be delivered on nearly any version of linux and / or unix.

After this course, you will be able to:

  • Setup and configure a basic linux installation
  • Configure and determine basic networking properties
  • Add users and groups, and change permissions accordingly
  • Work with common unix file system commands, like ls, mv, etc.
  • Control processes
  • Search for files and contents of files
  • Parse files using sed, awk, and grep
  • Automate simple tasks using shell scripts
  • Use cron to set background tasks
This course will be delivered in 5 Days

DI will work with you and your team to define the most appropriate delivery structure, schedule and dates. Structure, schedule and dates will be determined by project schedule, team availability and classroom availability. And of course, it will also be determined by DI’s instructor availability.
