docker run -it --rm -p 8888:8888 jupyter/datascience-notebook

How this works:

You can create a VERY similar interactive DEMO using just echo to display text and read to prompt the user to press ENTER for a new line.

Create a new script called demo.sh, and add the following text:

echo 'My presentation using just echo and read'
echo '========================================'
read

echo '- Bullet 1: echo command is similar to print() in python'
read
echo '- Bullet 2: read command is similar to input() in python'
read
echo '- Bullet 3: read will just wait for you to press ENTER'
read

Make the script executable and run it:

chmod +x demo.sh
./demo.sh

Result:

My presentation using just echo and read
========================================

- Bullet 1: echo command is similar to print() in python

- Bullet 2: read command is similar to input() in python

- Bullet 3: read will just wait for you to press ENTER

Run

./menu.sh

Dependencies:

• If it doesn't work.. run tools/install-docker-ubuntu.sh first

Or:

sudo apt-get -y install curl pv toilet dialog

Tools used

• dialog - creates menus
• figlet or toilet: creates titles in 'ASCII art'
• pv
• Demo Magic from https://github.com/paxtonhare/demo-magic

How it works:

• ./tools/init.sh - set up colors and demo-magic script
• ./tools/install-docker-ubuntu.sh - install prerequisities
• ./menu.sh - uses dialog to create a menu system.

How do bullets and text get displayed?

# Setup color / font variables in shell:
BULLET="\033[0;33m" # This creates yellow font when ran with `echo -e ${BULLET}`
RESET="\033[0m"     # This resets to normal fonts

# This ia function
bullet(){
    echo -e "${BULLET}• $@${RESET}" # This will echo a YELLOW bullet    
    read # This will read from the keyboard (no variable, so it just expects an ENTER)
}

bullet "Hello world" # This will display a YELLOW bullet with the text TEST and wait for ENTER

How is the menu created:

I'm using dialog. This can be installed with sudo apt install dialog. Tutorial: http://www.linuxjournal.com/article/2807

Simple example:

dialog --title "Message"  --yesno "Are you having fun?" 6 25
