Elements code tutorial
An easy way to run the main tutorial’s code
Rather than have to copy and paste or type in each line of code in the tutorial, you can use the code below.
Save the code in a file named runtutorial.sh and place it in your home directory.
To run this code just open a terminal in your $HOME directory and run:
bash runtutorial.sh
Then press the return key to execute each line in turn.
Note: If you want to run some of the steps automatically and then have execution stop and wait for you to press enter before continuing one line at a time: move the trap read debug statement down so that it is above the line you want to stop at. Execution will run each line automatically and stop when that line is reached. It will then switch to executing one line at a time, waiting for you to press return before executing the next command.
You will see that occasionally we will use the sleep command to pause execution. This allows the daemons time to do things like stop, start and sync mempools.
It is perhaps a good idea to have the relevant tutorial pages open as you run through this code for reference, as it is not itself annotated in any meaningful way.
There is a chance that the “ and ‘ characters may not paste into your runtutorial.sh file correctly, so type over them yourself if you come across any issues executing the code.
#!/bin/bash
set -x
trap read debug
# This code was originally based upon and expands the example found here: https://github.com/ElementsProject/elements/tree/elements-0.14.1/contrib/assets_tutorial
