UNIX is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center. The OS made it possible for a lot of users to interact with a single machine at the same time. Before, this was done by a batch process via an operator/administrator.

Rasperry Pi

Raspberry Pi is a small single board computer used for learning basic computer science.

Rasperry Pi

Basic tasks & experiments:

  • Logging into the Raspberry Pi
  • printing with Matrix printer, ascii word-art generator (more), text-to-speech
  • creating public_html directory and index.html on the Sandbox (note: remote login not possible)
  • modifying texts (bio) through Terminal using Dadadodo and SED (changing and replacing certain characters)
  • working with Unix HTML - editor: ne nice editor
  • chaining programs a.k.a PIPING (command: |) / concatonate files (command: CAT)
