This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "Requests for learning materials (tutorials, how-tos etc.) are off topic. The only exception is questions about where to find official documentation (e.g. POSIX specifications). See the Help Center and our Community Meta for more information." – terdon

What do you mean by "bash completion tutorial"? Please explain. – Patkos Csaba Dec 10 '10 at 21:14
the explanation is needed on the word "tutorial", what do you actually need? – phunehehe Dec 11 '10 at 0:26
@Tshepang: I guess you mean you want to learn how to write bash completion routines? Using bash completion is pretty easy, you just hit the tab key. – intuited Dec 11 '10 at 4:45

How come this question is considered "too broad" ? That's ridiculous. It's perfectly valid, and answers provided prove it's not so easy to find out. – Cyan Mar 19 '15 at 0:02

There aren't that many bash completion tutorials around, but this one is pretty good:

Introduction to Bash Completion

  • Part 1 is for general knowledge
  • Part 2 covers creating scripts in /etc/bash_completion.d/
