A course for anyone interested in understanding all aspects of the bash shell. Designed for use by beginners, it assumes as little knowledge as possible but teaches you all the intricacies of bash it took me decades to learn by trial and error. 

The interactive nature of the course instills the knowledge in a way you will not forget!

Master the Bash Shell

**Readline** is one of those technologies that is so commonly used people don't realise it's there. In this lesson I want to make you aware of it and introduce some concepts and examples of its use so you're able to deal with any problems that arise from its use or misuse.


### How Important is this Lesson? 

Writing bash does not require a knowledge of readline. Understanding
readline helps greatly to understand what is going on at the terminal
and at the command line.

### Bash Without Readline

First you're going to see what bash looks like without readline.

In your 'normal' bash shell, hit the `TAB` key twice. You should see
something like this:

```html
Display all 2335 possibilities? (y or n)
```

That's because bash normally has an *autocomplete* function that allows
you to see what commands are available to you if you tap `TAB` twice.

Hit `n` to get out of that autocomplete.

Similarly, if you hit the up arrow key a few times, then the previously-run
commands should be brought back to the command line.

Now type:
