How to start programming in Bash, without prior programming experience? And making sure it will be fun?
Basics
- Shebang, script files, make files executable, terminal screen, editor (I use Sublime Text)
- Display Hello, world!
- Variables (scalars): Assigning & displaying
- Commenting (
#) and documenting in a structured way - Receiving user input & processing it - E.g.: Ask the user for his/her name and displaying something like Hello, <name>!
- Comparisons, e.g., check for empty imput and take appropriate actions
- Flow control: Loops. E.g.: Display the numbers from 1 to 100 on the screen; With a step function; Backwards
- Pipelining. E.g.
ls > tmp.txt - Grep; Pipelining

Specifc & personal things
